FAQs

Recommendation cleaning

• Isopropyl alcohol → for diamond & jewellery surface
• Boiling hot water + a little soap + very fine new toothbrush

Learn more about the materials and their cleaning under Guide/Material and Cleaning.

Methylated spirits (colorless)

Colorless fuel is ideal for cleaning diamond jewelry (platinum & 18 carat gold). Because Sprit is highly degreasing, it dissolves grease, hand creams and dirt ideally. In addition, it evaporates with practically no residue and displaces water.

You can simply place your diamond jewellery in a bowl of sprit, possibly clean the surfaces and spaces gently (e.g. with a new fine toothbrush) and leave the jewellery in for a while. Then dry on a piece of paper or cloth.

In addition, you can quickly, easily and simply clean a grease-stained diamond and jewelry surface with a paper or cloth cloth soaked in fuel.

ATTENTION: is not suitable for other gemstones as these do not have the same hardness as diamonds and are often porous and sometimes contain oil as a component! Caution is also advised with metals that are not platinum or have less than 18 carats.

Hot Water & Flushing Agent

A simple plan to keep your diamond jewelry beautiful is to soak it in a gentle degreasing solution, such as water, with a few drops of mild dish soap. After removing the diamond from the cleaning solution, use a soft, clean toothbrush to remove any remaining dirt. The toothbrush should be new and used solely for cleaning your jewelry. Use them to clean hard-to-reach areas like the back of the diamond, where the most oil and dirt will accumulate.

Vinegar & salt?

Vinegar & salt is no problem at all for your diamond, which is the hardest and most resistant material (-> crystallized carbon). You can do it, but cleaning is not always that effective with it.

Professional cleaning?

Sometimes an ultrasonic cleaner is necessary to remove encrusted dirt on diamonds. A professional cleaning with ultra-sonic or an evaporation device combined with checking the «prongs» is a good idea.

“blue nuance” (hue) versus “icey white” Diamonds

Blue hue diamonds have a bluish undertone. The blue hue is a hint of blue color in diamonds caused by excess boron in the diamond (similar to “Fancy Color Blue” but much less solid). Laboratory diamonds with a measurable amount of boron are considered Type IIb and not Type IIa.

How is the blue nuance created?
Boron is often introduced during HPHT growth as a means of removing nitrogen. Removing boron after it has been introduced is very difficult and expensive.

HPHT Lab diamonds may have a bluish hue due to boron impurities → noted as “blue nuance” in the evaluation reports. Mine diamonds with blue hues are rare. Most diamonds typically have a yellowish hue due to nitrogen impurities → approximately from “I” on the “I-Z” color scale of “white diamonds”. If the goal is to find a Lab diamond that visually resembles the most common mine diamonds, then diamonds with a blue hue should be weeded out.

On the other hand, bluish is a popular and rare color in diamonds.

How does a “blue nuance” affect the price?
The slower and more carefully a HPHT diamond is grown, the less likely it is to have excess boron. Diamonds without blue nuance are much more expensive to grow and fetch a higher selling price.

How does this affect the diamond, apart from the colour?

Most importantly, the presence of boron can make a diamond electrically conductive. This is also the case with “Fancy Color Blue” diamonds. This means that a certified lab diamond may show up on some cheap diamond testers as a moissanite (which of course is wrong, after all you have an official certificate which was correctly issued as “diamond” with much more expensive and precise instruments and specialists). In addition, the presence of boron can cause a laboratory diamond to exhibit a medium to strong orange phosphorescence.

3 times Excellent/Ideal in Cut & Polish & Symmetry = “Triple Ex”.

Especially for round diamonds, the expression “3 times Excellent = Triple Ex” is a technical term for absolute top class → three times the very best category (Ideal or Excellent) for cut, polish, symmetry.

“Triple Ex” are diamonds that are classified in both Cut, Polish and Symmetry with an excellent in the diamond certificate -> 3 times excellent.

Since IGI “ideal” cut grade is even slightly better than excellent, “Triple Ex” of course also applies when a diamond has an ideal cut (although the wording is not 3x excellent).

IMPORTANT: IGI’s “Ideal” = better than GIA Excellent! (though both cuts are excellent).
IGI has an additional level for Best-of-Best of Excellent = ideal.
This sometimes causes confusion as people think it has to be 3x Ex but ideal is even better.

Triple Ex stones are classified as follows:

• ideal (better) or excellent cut
• excellent polish
• excellent symmetry

1. Bruted girdle
2. Polished girdle
3. Facetted girdle

“Bruted girdle“
The girdle may be bruted, i.e. rounded by grinding against another diamond. Bruted garlands have a frosty appearance and a grainy, sugary texture. This “beardy” texture is unique to diamonds and helps distinguish real diamonds from imitations.

Some cutters believe that polished or faceted rondelles reflect the interior of the stone, so they leave stones with K color or lower rondelles.

Bruted Girdles do have one drawback, however. During rounding and sanding, feathers or tiny cracks sometimes form along the round bar.

Polished Girdle
A clear and smooth polished girdle becomes a large facet that allows the viewer to see inside the stone.

Faceted Girdle (Belt)
Faceted rondels have numerous facets along the entire edge. Today, most diamonds, especially high quality stones, have faceted borders.

Faceted diamonds are first cut. Any tiny feathers or cracks created during the grinding process are then removed during the faceting process. The production of faceted rondelles therefore takes more time and may result in a slight loss of weight. However, they do give the diamond a cleaner, more finished look.

The rondelle itself is usually not visible to the naked eye unless the diamond is extremely large or the rondelle is unusually thick.

Bowtie effect (black shadow in the middle)

The bowtie effect is a black “stripe” through the center half of certain diamond cuts = shadows inside the diamond , created when light casts a shadow on the central facets. The reason for this is that it’s hard to avoid when cutting elongated shapes – their center sections are too long, and it can be difficult to grind the facets there to properly reflect the light. This black streak is not due to any particular chemical coloring inside the stone, nor is it due to any particular inclusion. It also has nothing to do with “light leakage” through the sides of the stone, which is one of the more common problems with diamonds.

The diamond bowtie effect is not always pitch black. Many loops are just slight shadows in the center of the stone that are barely noticeable. Almost all marquise, oval and pear shape diamonds have at least some loops, but they are often simply seamless and not as obvious. Some square shapes like the beam cut may also show loops.

Certain loops are even considered positive – if the loop effect is not too pronounced, and if the cutter has shaped the stone well around it, the loop can even add a certain sparkle to the stone and enhance its sparkle.

The presence of a “bowtie” is not listed in the report of a diamond. It’s important to note that a diamond bow tie is not necessarily a flaw – many fancy cuts will show some signs of a bow tie due to their complex faceting.

It’s all about your personal taste!

Did the diamond cutter do a bad job if a diamond doesn’t have a super cut?

Unfortunately, when most people look at a diamond, the carat size usually makes the biggest impression. In reality, the cut has a big impact on how big a diamond appears and the light pattern it shows. It also largely determines its brilliance – how much light it returns – and its dispersion – how much inner “fire” it shows. If the cut is done poorly, it can ruin these most valuable aspects of diamonds – not something you want!

These days, most diamonds are cut with lasers, so most diamonds should fall in the Very Good to Excellent range.

The only reason diamonds ever have a less than excellent cut is because the diamond cutter is trying to save weight. Cutting diamonds is usually a compromise between saving weight and maintaining good brightness, pattern and symmetry.

A diamond with a larger carat size simply fetches a higher price, even though it has a slightly lower cut. In other words, although a diamond with a lower cut will fall slightly in price, a larger carat size more than makes up for this deficit. However, if the cut is so poor that the diamond looks dumpy, its value would be diminished.

CAUTION: If you buy a stone with a less than excellent cut, you may have bought a thick stone that hides the weight but does not appear larger compared to smaller or equally sized stones. In addition, a poorly cut stone may also have less brilliance and fire than a comparable well-cut stone.

Recommendation: “ideal” & “excellent” (for round white diamonds), at least “very good”.

The cut is the most important criterion, more important than polish & symmetry!
Poorly cut diamonds can appear lackluster.
Cut contributes directly to the appearance of a diamond because it describes:???????

Yes!

We sell only lab diamonds (white and fancy color).
Also called: Lab diamonds, lab grown diamonds, laboratory-created diamond, lab diamond, man-made diamond.

Diamonds of the Future

• SWISS Made top quality jewelry
• Swiss pioneer & expert in Laboratory Grown Diamonds
• REAL diamonds (official certificates IGI, GCAL, GIA, etc.)
• Our lab diamonds are chemically, physically & optical identical to mined diamonds.
• Up to 70% cheaper than mined diamonds
• Affordable colored diamonds (Fancy Color Diamonds)
• Sustainable & environmentally friendly, social & ethical
  (ESG; SUSTAINABILITY)

Sometimes erroneously also called “synthetic”.
Synthetic is incorrect because crystallized carbon (which all diamonds are made of both lab diamonds and mine diamonds) is a naturally occurring substance on earth and nothing synthetic. In addition, there is a decision on this by the U.S. FTC.

Although with very small stones, e.g. 2mm, the work is more significant and the market/supply/availability of mine diamonds is greater (at least for the moment), we have decided to work exclusively with lab diamonds because of sustainability, environmental friendliness, sustainability, ethics and social aspects.

Yes, it is safe to buy engagement rings online if you choose a reputable and trustworthy jeweler . Look for positive reviews, safety certificates and quality.

PROFESSIONAL KNOW HOW ESSENTIAL
However, even with a certificate and videos, it is very difficult for laypeople to assess how good a diamond is and whether it has features that could negatively affect its longevity and beauty.
The 4C’s are only Basic, also the bandwidth even within e.g. VVS Clarity is very large (VVS is not equal to VVS). You can’t see everything in the certificates! There are also many other things to consider e.g. Inclusion Type & Location, Milky, Brown, Gray, Green or Blue Shade, Nuance, blue Tinge, external Characteristics, inclusions that come to the surface or to the edge, Girdle etc.
Therefore, the help of a professional and trust are essential.

BIG DIFFERENCES IN QUALITY
Laboratory Grown Diamonds are available in “Low Quality” and “High Quality”.
In order to accurately assess the quality differences between low and high quality, one must be very familiar with the processes and methods and how that laboratory manufactures. There are great differences in both white rennet diamonds and colored rennet diamonds. Fancy Color Diamonds: For example, there are stones that are only “coated”, that is, they have only a thin color coating that is not durable and fades, gets scratches or dissolves.

Official certificates of gemmological laboratories:
With no other gemstone do you have such an exact description and classification of the diamond with the certificates issued by independent gemmological laboratories.
→ it can be said very precisely what kind of stone this is.

Videos:
With the videos you get on the mobile phone (-> smaller picture) a very good impression of the form, brilliance, sparkle and the color of the diamond and on the PC (-> larger picture) you see the stone in X-fold enlargement very exactly. E.g. seeing imperfections in clarity and how good the diamond is. You will also be able to see polishing imperfections in a diamond with a lower polish grade.
It is a misconception to think that you can see more with the naked eye in a shop with optimal lighting.

We love IF and VVS purity Lab Grown Diamonds, laboratory diamonds.

✓ more valuable: The more free of inclusions (better clarity), the more valuable the diamond is. IF and VVS diamonds are more valuable.

✓ Investment: Top quality diamonds are preferred as investments. IF and VVS diamonds are better suited as an investment.

✓ better for large diamonds: The larger the diamond, the more likely you are to see inclusions. IF and VVS diamonds are also very beautiful in large sizes with a lot of carat.

Incredibly rare, flawless and internally flawless stones make up only 2% of gem quality diamonds. This is why they fetch high prices, especially in large carat sizes.

You will notice a huge price difference between an IF stone and a VVS stone. Since IF Internally Flawless is extremely rare, even with Lab Grown Diamonds, the price jump from VVS to IF is massive. As purity levels go down, price differentials decrease exponentially.

I.F. Internally Flawless (I.F.)

• No defects visible under 10x magnification
• No inclusions visible under 10x magnification
• Loupe Clean at 10x magnification = Loupe Clean (LC)

VVS1 & VVS2 Very Very Slightly Included

• More valuable
  The more free of inclusions (better clarity), the more valuable the diamond is
• Investment
  Investments → Top-quality diamonds are preferred as investments
• better for large diamonds
  The larger the diamond, the more likely it is that you will see inclusions
• Minimal inclusions, very difficult for an experienced grader to recognize at 10x magnification
  

Very Very Slightly Included (VVS):
VVS stones have tiny inclusions that are so small that they are barely visible under 10x magnification. Most consumers probably can’t tell the difference between F, IF and VVS diamonds.

Every stone in the VVS range still has extremely high purity and fetches a top price.

Diamonds with the grade VVS1 and VVS2 have an excellent clarity.

The imperfections in VVS diamonds are only visible under high magnification. Even a jeweler’s loupe is sometimes insufficient to see these imperfections.

Big diamonds:
The larger the diamond, the more likely you are to see inclusions, especially if they are in the center of the diamond, under the table. The tablet is the large facet at the very top of the diamond where most of the light enters the stone.

The larger the stone, the more visible the inclusions, simply because you have more surface area to look at. For stones much larger than one carat, look for a purity grade of VS or higher. For stones of one carat or less, VS or even SI grades are the standard. For small stones (less than half a carat), purity is not as important. The color grade is more striking.

Clarity is an important consideration when you are looking to buy a diamond. At the upper end of the purity scale, though not quite at the top, are VVS1 diamonds (very very slightly included). These are considered to be of excellent purity and are correspondingly more expensive (whereby with the rennet diamonds the price difference becomes greater to the advantage of the rennets the purer the stone is → it is therefore worthwhile 😉

When it comes to buying a diamond, the cut is probably the most important of the four C’s. A good cut brings out a fire and brilliance that can offset (and even hide) flaws and coloration.

Nevertheless, clarity can also have an impact on the beauty of the diamond you choose. Inclusions affect the way light reflects from the diamond back to you. The more inclusions, the less fire and brilliance a diamond will have.

When looking at diamonds, make sure you are magnifying them to see flaws and inclusions → video on PC.

What does the purity VVS1 mean?
Diamonds are graded on a clarity scale that measures how clear the diamond is and how many flaws or inclusions the diamond has, both internally and externally, when viewed at 10x magnification. Flaws and inclusions can be anything from small cracks or chips on the surface of the diamond to tiny crystals that were embedded when the diamond was formed.

It is quite difficult to find a diamond completely without a flaw. Even FL diamonds, which are considered to be flawless, can have flaws if they are viewed under a sufficiently high magnification.

VVS diamonds, whether VVS1 or VVS1, are very, very easily included. Despite some inclusions, these diamonds are considered to be of excellent clarity.

Remember that jewelers grade diamonds by clarity by looking at them under 10x magnification. So although flaws may be visible under magnification, a diamond (especially a VVS diamond) is most likely what is called eye clean.

This means that the diamond looks flawless to the naked eye. A VVS1 diamond will definitely look flawless even if you turn it in the light.

Very Slightly Included (VS) = “eye clean”:
VS stones are in the upper to medium range of diamond clarity grades. They have minor inclusions, which means that they do not affect the purity much, even if they are larger or more numerous than in VVS stones.

Although VS diamonds have a lower clarity grade, you usually cannot see their imperfections with the naked eye with VS1. VS1 is usually eyeclean. However, this does not necessarily mean that this diamond has no inclusions or other blemishes that could negatively affect its longevity.

In addition: The inclusion types, inclusion location, inclusion frequency, etc. is different.

→ we help you find a “top VS diamond”.

Slightly Included (SI):
SI bricks are of commercial quality. The inclusions are visible at 10x magnification, but most likely not to the naked eye. But “eyeclean” cannot be guaranteed. Still, an SI stone can appear duller and less brilliant, especially to someone familiar with fine jewelry.

Included (I):
In general, it’s not a good idea to buy I stones, even if they are technically gem quality. I diamonds have inclusions that are visible even to the naked eye. Furthermore, these inclusions can even affect the durability or wearability of the diamond, especially with I3 stones.

Should I buy a diamond as an investment?

Diamonds are known as an investment, and this goes back a long way in history.
It is valued that diamonds are timeless (often inherited), practically indestructible “forever” and concentrate a lot of money in an extremely small space.

Top qualities in terms of color and clarity are preferred as an investment.

Larger diamonds are also more interesting as an investment (more carats).

Fancy color diamonds are also popular investments.

A diamond will certainly always fetch a certain price. Not like a zirconia that goes straight down to zero after purchase. And of course, a real diamond is a beautiful thing/jewelry to enjoy.

Whether it is a good investment depends on the price development. This question applies equally to real diamonds from the laboratory (lab diamonds) and to mine diamonds.

For “white diamonds” in particular 1 carat is a very decisive value/price limit.

Stones below are worth massively less.

→ We therefore recommend that the “center stone”/main stone of white diamonds be over 1 carat.

It is different with fancy color diamonds, where even stones under 1 carat can be very valuable.

→ We recommend that the “center stone”/main stone is over 0.5 carat.

Recommendation: “bigger is better”, “size matters”, “big is beautiful“.

“MAGIC SIZES:

• 0.5
• 0.75
• 1 Carat

Visually, there is hardly any difference between a 0.99 carat and a 1.00 carat diamond.

→ But: usually considerable price difference!

They are called “magic sizes” because the price “magically” jumps once it reaches 1 carat and other large fractions, mainly every 1/4 carat.

Large gemstones are much rarer than small ones, which makes large diamonds much more valuable

Diamond prices rise exponentially with the carat weight.

Thus, a 2-carat diamond of a certain quality is always worth more than two 1-carat diamonds of the same quality.

This means that the price per carat (carat price) is generally much higher for a 2-carat diamond than for a 1-carat diamond.

Yes! There was an important change in the law in the U.S. in July 2018 by the U.S. Federal Trade Commission (FTC) this states “diamond = diamond”, regardless of origin, whether from the lab or from the mine. Furthermore, today the most prestigious international gemological laboratories (IGI, GCAL, GIA) certify lab diamonds with the same classifications, the 4 C’s, as mine diamonds.

Lab diamonds are up to 70 percent cheaper than mine diamonds. For colored diamonds – Fancy Color Diamonds yellow, blue, pink and others – the price differences are even greater. Another advantage is that lab diamonds are more sustainable, environmentally friendly, social as well as ethical from their conflict-free origin. They are guaranteed not to be blood diamonds.

Main reasons in favor of Lab Grown Diamonds

• genuine diamonds (official certificates IGI, GCAL, GIA, etc.)
• Our lab diamonds are chemically, physically & optical identical to mined diamonds.
• up to 70% cheaper than mine diamonds
• affordable colored diamonds (Fancy Color Diamonds)
• Sustainable & Environmental & Social/Ethical (ESG; Sustainability)

→ the question is not why buy a lab diamond, the question is why NOT to buy a lab diamond and a mine diamond?!

…diamond = diamond. This was defined by the FTC (USA Federal Trade Commission) in July 2018.

All diamonds consist of pure cubic crystallized carbon.

Chemically, physically, optically, lab diamonds are the same as mining diamonds.

Both are 100% pure crystallized carbon.

Difference: origin laboratory versus mountain mining. Lab diamonds are 100% genuine, cheaper, more sustainable and more ethical. We see no reason not to buy a lab diamond.

Laboratory diamonds are expensive to produce. Therefore, they will always have a certain value!

They are 100% genuine diamonds made from the same material as mine diamonds (carbon, pure carbon). Cultivation takes weeks, months, sometimes even years and requires state-of-the-art technology with expensive machines and entire teams of technicians and engineers. Laboratory diamonds also have to be cut, polished and certified.

Laboratory diamonds (lab diamonds) also have a secondary market, so there are certainly lab diamond buyers. You can also sell your Lab diamond to a private person, you have all the official certificates.

Lab diamonds also have price fluctuations on both sides. Exactly the same as mining/mining diamonds.

The question of the resale price naturally also arises with mine diamonds.
If diamond prices fall in general, e.g. both types fall -10%. Then you will lose the same amount in percentage% for the Lab diamonds, but in absolute figures (i.e. francs) you will lose less money than for the mine diamonds because the price of Lab Grown diamonds is lower.

→ in this scenario you would be better served with the Lab diamond.

In our opinion, the price difference between rennet diamonds and mine diamonds is too great (i.e. rennet diamonds are too cheap) and we expect prices to converge. This means that rennet diamonds could become more expensive, for example if the demand for rennet diamonds increases.

→ in this scenario you would be better served with the Lab diamond.

No problem!

We have various solutions for you!

1. Multisizer & ring dipstick (ring available) & ring size models

• With the multisizer (plastic knife) you can measure the finger. ATTENTION: remember, the ring must go over the knuckle “Knödli” (i.e. don’t just lace it to the back of your finger and read off the number, but make sure the plastic ring is tight to the knuckle but still goes over it).
• You have a ring for the finger you want? With our ring gauge we can easily determine the size.
• Metal rings for size measurement can be used well if there is the possibility to try on this metal ring.

2. Plastic model with zirconia

You are not sure 1) about the size or 2) about the design? No problem, with us you have the possibility to have plastic models made before the production of your piece of jewellery.

Almost all women and men love big diamonds. That’s why real Lab-Grown diamonds are ideal!
=> You get more diamond for your money.

1. Optimize the size (carat) first:
   “bigger is better”, “size matters”…this is the most obvious marker that is often asked about and that everyone knows…
   
2. Select the shape / form in the 2nd step:
   Round, oval, emerald, heart etc.
   
3. Only in the 3rd step select the color (Color), purity (Clarity), etc.

We will be happy to advise you → contact us.

The first question you should ask yourself is: what look/charisma do you want? Brilliant sparkling or prefer cool clear icy look? Maximum sparkle or a special shape?

3 diamond cut types:

• Brilliant cut → the most sparkle due to their ideal facet pattern
• Step cut → not as much sparkle, but are appealing because of their style
• Mixed grinding

Charisma:

• Brilliant sparkling diamonds (brilliant or mixed cut)
  • Round (= Brilliant)
  • Marquise
  • Heart
  • Pear
  • Cushion (= Cushion modified Brilliant)
  • Radiant (= Cut-Cornered Rectangular modified Brilliant)
  • Oval
  • Princess
• Cool clear icy look (step cut)
  • Emerald
  • Asscher (= square Emerald)

If you want a “sparkle & brilliance” to it: ideal to combine: Eternity ring with many small sparkling diamonds to it.

Do sharp corners and edges bother you? If so, we recommend:

• Round
• Oval
• Cushion
• Emerald & Asscher (if cool clear icy look desired)

You can’t go wrong with a round diamond (= brilliant). They sparkle the most and are the best selling shape. They are classic, timeless and never go out of fashion.

In addition, round diamonds are also cut/cut graded, so you can tell quite accurately if this is a “good” stone or not.

From very large sizes, e.g. 10 carats (14mm = 1.4cm diameter), it may be that the round shape is too wide for the ring on your finger and therefore an oval shape is more attractive.

IGI Cut Grades -> is “ideal” better than “excellent”?

Yes! IGI has made an additional higher category for the top-of-top stones of excellent = ideal.

Ideal = Top cut grade from IGI, which is higher than excellent.

At GIA, the highest cut grade is excellent and corresponds to IGI excellent.
The five criteria that IGI primarily uses to classify the cut of a diamond are: Total Depth, Girdle Thickness, Pavilion Depth, Crown Angle, and Table Width.

IMPORTANT: IGI’s “Ideal” = better than GIA Excellent.

IGI has an additional level for Best-of-Best of Excellent = Ideal.

Whereas both ideal & excellent are really excellent!

If a diamond has an identification number, it is engraved here by laser. The Inscription is like the social security number of the diamond. It identifies the diamond and assigns it to a specific grading report.

We think that the massive price difference of about 70% between mined diamonds and lab diamonds cannot be sustained in the longer term. Since both are identical products (chemically, physically and optically), theoretically the price difference cannot be justified anyway.

Due to the ecological footprint, it would also be conceivable that in the future lab diamonds might even become expensive.

We see the risk of mining diamond prices falling/correcting as very high.

Due to a strong increase in demand for lab diamonds, prices here could rise because the global supply is currently still small due to capacities and cannot be increased massively so easily.

→ it is a 100% real diamond

→ also crystallized carbon

→ chemically, physically and optically identical to mine diamonds

→ state-of-the-art technology with expensive machinery and entire technicians and engineering teams.

→ It takes several weeks, usually months, sometimes even years for a lab diamond to grow.

→ the rough diamonds, like mine diamonds, must also be elaborately and perfectly polished

→ Certifications by renowned, internationally recognised gemmological institutes (certification companies)

→ we have our lab diamonds exclusively from the best laboratories worldwide

Transport & insurance etc. is important and not quite simple and expensive.

The grading report of a diamond is like its identity card. Gemologists can confirm a diamond’s identity based on its cut angles, clarity flaws, and girdle inscription.

The report will also tell you if a diamond was mined from a mine or produced in a lab, or if it has undergone treatments. In combination with the four Cs (color, clarity, cut and carat), you can determine the quality of the diamond.

A diamond grading report gives you peace of mind that the diamond you pay for is the one you get.

The cut proportions and clarity characteristics act as a sort of “fingerprint” for your diamond, allowing others to confirm that it is the same diamond on your report.

Laser engraving with number on the girdle of the diamond

All Green World Diamonds (except the very small diamonds) have a laser engraving with a number (girdle/belt inscription with the report number) you can read this number with a magnifying glass on the diamond girdle and this is also written on the certificate. This gives you optimum certainty and security.

The certificate also states that it is

1. is a real diamond “Diamond”
2. is a Lab diamond
3. whether it was bred with HPHT or CVD

ATTENTION with “own certificates” = brand or shop diamond grading

Some brands/sellers have their diamonds graded internally instead of sending them to an outside gemological lab. While a few are remarkably consistent, like Tiffany & Co, most have somewhat loose standards → uncertainty about quality (Color, Clarity, etc.)!

✓ Lab Grown Diamonds are real diamonds. Lab diamonds are 100% real real diamonds!

✓ Crystallized carbon
-> Pure Carbon from which both lab diamonds and mine diamonds are made

✓ Lab diamonds are chemically, physically and optically identical to mine diamonds
(this is also stated on the Lab Grown Diamond certificates)

✓ official certificates from independent certification companies (gemmological laboratories) such as IGI, GCAL, GIA, etc.

Yes! Lab-produced diamonds are real diamonds, identical in every way (except price!) to diamonds mined from mines. The labs crystallize carbon into stunning rough diamonds, which are then cut, polished and graded just like diamonds mined from the earth. Those produced in the laboratory have identical chemical, physical and optical properties. They have the same refractive index, dispersion and hardness and are graded by leading independent gemological institutes to the same standards as mine diamonds.

✓ Diamond = diamond (regardless of origin)

Important July 2018 U.S. Federal Trade Commission (FTC) Legislative Change:

“Lab grow diamonds” = diamonds, so do “(natural) mine diamonds”. The FTC says: A diamond is a diamond regardless of its origin . “a diamond is a diamond” no matter of it’s origin.

… “removed a section on misleading illustrations, and eliminated the word “natural” from the definition of diamond in section 23.12(a)”….

https://www.ftc.gov/news-events/blogs/business-blog/2018/07/diamonds-pearls-revisions-ftcs-jewelry-guides

-> YES!

Diamonds are a fashionista’s best friend – but the definition of the precious gemstone is changing thanks to new, emerging jewelry technology.

Not only are the prices of rennet diamonds lower than mine diamonds but the ethical sourcing and sustainability is slowly but surely making this trend mainstream. So it’s also becoming increasingly popular with celebrities, influencers and consumers. With the proliferation of Lab diamonds, more and more celebrities are also wearing these pieces of jewelry on the red carpet – many of whom are eco-friendly activists and human rights advocates.

Examples of stars with Lab diamonds:

• Drake: 2022 Drake (Mr. Champagne Papi) wears a 2 Mio Lab-Diamonds necklace designed by FRANK OCEAN
• Leonardo DiCaprio: Investor in lab-diamond technology

• Lady Gaga: September 2018 the London premiere of “A Star is Born”: cluster earrings made of three freshwater pearls and nine brilliant-cut lab diamonds

• Emma Watson: 2018 at the Academy Awards afterparty of the Vanity Fair Oscars: multitude of ethically made accessories with lab diamonds

• Meghan Markle: January 2019 at an event in London: yellow gold lab diamond earrings

• Camila Mendes: November 2018 People’s Choice Awards: 5-carat pink lab diamonds set on a 14-carat gold band

• Bindi Irwin (daughter of the late crocodile hunter Steve Irwin; conservationist): July 2019 engagement ring: it contains a Lab diamond and is made of rose gold. Chandler was incredibly thoughtful when he chose it, the ring captures the essence of who I am (with its vintage flair).

• Zoe Kravitz: 2019 Met Gala: A pair of dazzling earrings. The statement jewelry featured a feathered design accented by pearls and lab diamonds

• And many more stars….

1. difference: origin of laboratory versus mining

The difference between lab-grown and mine diamonds could be compared to the difference between ice that forms outside on a winter day and ice that forms in your refrigerator. Since mine diamonds are ancient, a more apt comparison might be between ice from an ancient glacier and ice from your fridge. But either way, both are ice. Both are frozen _H2O, regardless of origin.
Lab diamonds are chemically, physically and optically identical to mine diamonds!

2nd difference: growth morphology in the rough diamond
→ but is irrelevant for the polished diamond (because the “inside” is identical)

✓ Growth morphology in rough diamonds does NOT play a role for polished diamonds!

Where Lab diamonds differ from mining diamonds is the growth morphology in rough diamond: Mining diamond → Octahedron (like 2 pyramids together), HPHT → Cuboctohedron (sphere like honeycomb shape), CVD → Cube. But both are on the inside, namely in a cut diamond/brilliant, not able to be differentiated from each other! → irrelevant!

Yes! In the cultivation of lab diamonds, natural conditions are imitated.

HPHT = ✓ conditions analogous to those in the Earth’s deep interior

CVD = ✓ conditions analogous to interstellar gas clouds.

During this “growing process” the exact same inclusions can occur as with mine diamonds.

The inclusion types of lab diamonds are also found in mine diamonds. So they are not different/different types of inclusions. Only: a few mine diamonds have so-called “natural inclusions”. Analogous to a mosquito in an amber. Such inclusions do not occur in lab diamonds in the “clean” lab environment.

Still, Lab diamonds often even a better color and purity (= quality). Partly Lab diamonds are even harder than mine diamonds because of a better “compression”. Nevertheless, inclusions also occur in rennet diamonds.

We also have the impression that with lab diamonds from the best laboratories with excellent quality, the inclusions are often very local and the “rest” of the diamond is “crystal clear”, whereas with mine diamonds, small inclusions can often be observed throughout.

No. Even experts with common instruments and diamond detectors, UV light, magnifying glass etc. are not able to tell the difference.

Lab-grown diamonds are identical in appearance to mine diamonds (visually identical)!

✓ traditional gemmological observations and old style “diamond detectors” are NOT able to distinguish them

In order to detect possibly very subtle differences in growth morphology, gemological institutes had to develop extremely expensive and complex equipment specifically for this purpose.

Certification laboratories try with special very expensive and complex machines and specifically trained experts (specially trained gemologists) to assign the difference by means of growth morphology (which is irrelevant in the cut diamond) and here more common fluorescence patterns under the UV light.

But even that is extremely difficult!

Moreover, even if growth patterns should be detected, it does not change the fact that “diamond = diamond”, it is a real diamond with the same material (crystallized carbon, pure carbon), the same chemical composition (chemically, physically and optically identical) and the same crystal structure as a mine diamond.

How do the certification companies manage to identify Lab-Diamonds as such?

As you can see, it is extremely difficult to make this distinction even for extremely well and very specifically trained experts who have specially developed equipment.

They try to categorize the morphology of diamonds using a diagram that lists the growth process, typical growth morphology and visual examples of mine, HPHT and CVD rough diamonds.

This diagram shows the different rough diamonds based on their growth form, or growth morphology. Although this shape is lost after a diamond has been cut and polished, identification is still possible by looking for fluorescence patterns (under the UV light) resulting from, among other things, the particular growth morphology – a difficult task!

As a rule, the cut diamonds are sent to the certification companies already declared as “lab grown”.

In the growing process, the natural growth

1. in the deep interior of the earth (HPHT) or
2. in interstellar gas clouds (CVD)

is mimicked or imitated. The crystallization of the carbon takes place over months, depending on the size.

Subsequently, the grown rough diamond is cut, polished and cut by a diamond cutter.

LGD = Lab Grown Diamond.

What is a Lab Grown Diamond?

A “Lab Diamond” is a man-made diamond that has been grown in a laboratory environment by one of the two currently available manufacturing processes: HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). All real diamonds consist of pure crystallized carbon (pure carbon); this applies to both mine diamonds and lab diamonds. The growing process mimics/imitates natural growth in the deep interior of the Earth (HPHT) or in interstellar gas clouds (CVD). Although the growth process is different from what occurs in nature, the chemical composition, physical properties, and optical characteristics of lab-grown diamonds are identical to those of diamonds mined/extracted from mines. Lab-grown diamonds come in all sizes (2022: cut up to 30 carats), all shapes and all colors, and the light output is identical to that of mined diamonds.

Also called: Lab diamonds, lab grown diamonds, laboratory-created diamond, lab diamond, man-made diamond, green diamond, green diamonds.

CVD (Chemical Vapor Deposition)

A CVD diamond (Chemical Vapor Deposition) is a grown laboratory diamond (Lab Grown Diamond), a real diamond made of crystallized carbon. It is chemically, physically and optically identical to mine diamonds. At Green World Diamonds you get certificates from renowned gemmological laboratories like IGI, GCAL, GIA etc.

There are white and colored CVD diamonds (White and Fancy Color Diamonds).

In CVD synthesis, microwaves split the hydrocarbon molecules fed into the reactor. These fragments migrate downward to the colder diamond nucleus and attach to the growing diamond surface. The Lab diamond grows in thin layers, and its final thickness depends on the time available for growth. The result is flat, tabular crystals (similar to a cube) whose outer surface is coated with black graphite.

✓ Analogous conditions of interstellar gas clouds (how cool is that?)
✓ Vacuum chamber
✓ Approx. 1,000° Celsius (high temperature, lower than HPHT)
✓ Microwave beam

HPHT (High Pressure High Temperature)

A HPHT diamond (High Pressure High Temperature) is a lab grown diamond, a real diamond made of crystallized carbon. It is chemically, physically and optically identical to mine diamonds. At Green World Diamonds you get certificates from renowned gemmological laboratories like IGI, GCAL, GIA etc.

There are white and colored HPHT diamonds (White and Fancy Color Diamonds).

In HPHT synthesis, a press applies extremely high pressures and temperatures to a central growth chamber containing the necessary ingredients. This results in lab diamond crystals with combinations of cubic and octahedral faces. Similar to a honeycomb structure with squares.

✓ Analogous conditions deep inside the earth
✓ Approx. 1,500° Celsius (extremely high temperature)
✓ 400 tons per square inch (extremely high pressure)

How do laboratory-grown diamonds differ from mine diamonds?

There is actually no difference: both are 100% real diamonds made of crystallized carbon with an identical cubic lattice structure. Mine diamonds are mined, laboratory diamonds are produced in the laboratory – but chemically, physically and optically they are completely identical. In 2018, the US FTC changed a law: “A diamond is a diamond, regardless of its origin.” International gemological laboratories (IGI, GIA) therefore certify lab diamonds with the same criteria as mine diamonds. Even with diamond detectors and traditional gemmological methods, they are indistinguishable.

Why is a reputable supplier of laboratory diamonds so important?

💎 Are there counterfeits of laboratory diamonds?
Yes! The market for laboratory diamonds is growing, but unfortunately there are also more and more counterfeits. Some suppliers sell moissanite or other imitations as genuine laboratory diamonds – often even with forged certificates.

💎 How do I recognize a genuine laboratory diamond?
A genuine laboratory diamond is chemically and physically identical to a natural diamond. It should always be supplied with a certificate from a recognized institute such as GIA, IGI or HRD. Make sure that the certificate has not been tampered with or falsified.

💎 What should I look out for when buying?
✔️ Only buy from trustworthy jewelers or dealers.
✔️ Ask to see the certificate and check it online with the issuing institution.
✔️ Be careful with extremely cheap offers – they are often deceptive.

💎 Why should I choose a reputable provider?
A reputable provider guarantees the authenticity and quality of your laboratory diamond. This means you get exactly what you ordered: a stunning, certified diamond that will sparkle forever. ✨

Are there differences in the quality of laboratory diamonds?

Yes, just as with natural diamonds, there are also major differences in the quality of laboratory diamonds. The most important factors that influence quality and value are:

💎 1. clarity:
Laboratory diamonds can have inclusions, just like natural diamonds. High-quality stones have minimal or no visible inclusions (e.g. VVS or VS1).

💎 2. color (Color):
The best laboratory diamonds are colorless or almost colorless (D-F). Cheaper varieties may have a slight yellow or brown tint.

💎 3. cut:
The cut is decisive for the sparkle of the diamond. An excellent or very good cut maximizes the brilliance, while a poor cut makes the stone appear dull.

💎 4. growth method:
There are two main methods for producing laboratory diamonds:
✔️ HPHT (High Pressure High Temperature): Often yields clearer stones with less nitrogen impurities.
✔️ CVD (Chemical Vapor Deposition): Sometimes results in color changes that are corrected by post-treatments.

💎 5. certification:
Reputable laboratory diamonds have a certificate from GIA, IGI or HRD. Without certification, there is a risk of counterfeits or inferior stones.
Unfortunately, certificates are often falsified and sold as genuine laboratory diamonds with fake laboratory diamonds such as moissanite or other imitations – choose a reputable supplier with experience!

⚠️ Caution: Cheap laboratory diamonds can have poor cuts, inclusions or color casts. A trustworthy provider will ensure that you receive a high-quality, radiant diamond. ✨

Are there differences in the quality of laboratory diamonds and what should you look out for when buying them?

Yes, the quality of laboratory diamonds also depends heavily on the manufacturer. Different companies use different technologies, machines and manufacturing processes that affect the purity, color and overall quality of the diamond.

🔬 1. growth speed & technology:
Some manufacturers speed up the growth process too much, resulting in inferior crystals with more inclusions and color casts. High-quality suppliers take more time for growth in order to achieve perfect crystal structures.

🏭 2. machines & research teams:
The quality depends heavily on the machines used and the expertise of the research team. Modern and well-maintained machines produce clearer and more brilliant stones.

⚙️ 3. starting materials & consumables:
The quality of the seed crystals (seeds) and the gases used influences the purity of the laboratory diamond. In addition, consumables such as reactor chambers must be replaced regularly, as worn parts can lead to contamination.

📈 4. post-treatment & quality control:
Some manufacturers optimize their stones with additional processes to improve color and purity. Reputable suppliers rely on strict quality controls, while cheaper producers bring stones with undesirable color nuances or inclusions onto the market.

✅ Conclusion:
Not all laboratory diamonds are the same! High-quality manufacturers invest in research, state-of-the-art technology and careful production processes, while low-cost suppliers often make compromises. It is therefore crucial to only buy laboratory diamonds from reputable sources with reliable certificates.

Why are some laboratory diamonds milky or less brilliant?

Some stones have internal stresses or “graining”, which leads to a milky appearance. Inclusions and growth structures can also refract the light and reduce the brilliance. High-quality laboratory diamonds with an excellent cut reflect light optimally.

Is a GIA or IGI certificate important for laboratory diamonds?

Yes! A GIA or IGI certificate confirms that the diamond meets genuine quality standards. It contains important information on color, clarity, cut and carat weight. Dubious suppliers sometimes sell laboratory diamonds without a certificate or with falsified papers – so always make sure you are dealing with a reputable laboratory!

Is everything on the laboratory diamond certificate? Is it enough if I look at the certificate?

No, the certificate alone is not enough. There are many important aspects that are not listed on the certificate, such as the actual brilliance, the growth pattern or any treatment methods. There are also forged certificates and attempts at fraud in which moissanite or inferior stones are passed off as high-quality laboratory diamonds. It is therefore essential to buy from a reputable supplier who uses trustworthy laboratories such as GIA or IGI and checks the quality of the stones themselves.

How do I recognize a genuine laboratory diamond?

A genuine laboratory diamond is chemically and physically identical to a natural diamond. To avoid fakes such as moissanite or CZ, the diamond should be certified by a renowned laboratory such as GIA or IGI. The retailer should also be trustworthy and offer transparency regarding origin and quality.

Why are not all laboratory diamonds the same?

The quality of laboratory diamonds depends on the manufacturing process, the technologies and the source materials. Some manufacturers grow their diamonds faster, which can lead to more inclusions. The color control and purity of the final product also vary. High-quality laboratory diamonds have a uniform color and high transparency.

Can laboratory diamonds increase in value?

Lab-grown diamonds are primarily known for their affordability and ethical origin. The value can fluctuate as, unlike natural diamonds, they are not rare. However, particularly large and rare shades are gaining in importance, especially with high purity and certification.

Are there fake certificates for laboratory diamonds?

Yes, there are fake certificates and dubious dealers who sell moissanite or inferior stones as laboratory diamonds. To be on the safe side, the certificate should come from recognized laboratories such as GIA or IGI and the engraving number on the diamond should match the certificate.

How exactly are lab-grown diamonds cultivated?

The laboratory diamond growth process imitates natural growth in the Earth’s interior (HPHT) or in interstellar gas clouds and ice planets such as Neptune and Uranus (CVD). Carbon crystallization takes weeks to months. The rough diamond is then cut and polished. This procedure has various advantages: Green World Diamond’s laboratory diamonds are up to 95 percent cheaper, environmentally friendly and ethically harmless. We therefore fulfill modern ESG criteria. We can rule out “blood diamonds” that are mined under questionable conditions. And for one carat of mined diamond, around 250 tons of rock are extracted and 500 liters of water are polluted. “Solar lab diamonds”, on the other hand, are often CO2-neutral.

What is the difference between CVD and HPHT laboratory diamonds?

• CVD (Chemical Vapor Deposition): This method produces diamonds layer by layer under controlled conditions. CVD diamonds are often more stable in terms of color, but sometimes require post-treatment.
• HPHT (High Pressure High Temperature): Here, high pressure and high temperature are used to simulate natural growth conditions. HPHT diamonds often have a higher purity and richer colors.

Can a laboratory diamond lose its shine?

No. Laboratory diamonds consist of pure carbon in crystalline form, just like natural diamonds. They are extremely hard (10 on the Mohs scale) and retain their shine forever. Dirt and grease can dull the surface, but with a simple cleaning (e.g. spirit, warm soapy water and a soft brush) it will always remain shiny.

How does a laboratory diamond differ from a moissanite?

Although moissanite is often sold as a diamond alternative, it is a completely different material with a different refraction of light. Moissanites often have a stronger “rainbow effect” and are massively less valuable. A genuine laboratory diamond shows classic white fire and should be confirmed with a certificate from GIA or IGI.

Are laboratory diamonds sustainable?

Yes, laboratory diamonds have a significantly smaller ecological footprint than natural diamonds. They are produced under controlled conditions without environmental destruction or conflict financing. However, there are differences here too – some manufacturers rely on 100% renewable energy, while others use a lot of electricity from fossil sources.

Why should I only buy laboratory diamonds from a reputable dealer?

Because there are forgeries, manipulated stones and poor quality on the market. Reputable dealers offer:
✅ Genuine certificates (GIA, IGI, HRD)
✅ Precise information on cut, purity and color
✅ Origin and production methods
✅ No hidden moissanite or simulated diamonds

If the price sounds too good to be true, it usually is!

Why are some laboratory diamonds cheaper than others?

Price differences result from various factors:

🔹 Quality: Better color, clarity and cut mean higher prices. Diamonds with visible inclusions or a weaker cut are cheaper, but reflect less light and sparkle less.

🔹 Manufacturing process: High-quality laboratory diamonds grow slowly and in a controlled manner, resulting in better crystal structures and less internal stress. Fast-grown stones may have more inclusions or undesirable color shading (so-called shades or tints).

🔹 Hidden color casts: Some lab diamonds have subtle brown, gray, green or blue tints that are not always mentioned on the certificate. These can affect the brilliance and are a reason for lower prices.

🔹 Inclusions with long-term risk: While many inclusions are only visually disturbing, there are some that reach the surface or create internal stresses. These can affect the longevity of the diamondin the long term, as they can lead to cracks in the event of impact or setting tension.

🔹 Certification: GIA and IGI-certified stones are often more expensive as they are subject to strict tests. Without renowned certification, there is a risk of inferior quality or manipulated information.

Cheap laboratory diamonds are not always a bargain – there are often differences in quality that are not apparent at first glance. That’s why a reputable dealer with transparent information is particularly important!

How do I recognize a high-quality laboratory diamond?

A quality stone should:
✅ Have a GIA or IGI certificate.
✅ Have a high color grade (D-F) and excellent cut.
✅ Have no strong inclusions or surface features.
✅ Have no disturbing color casts such as brown, grey or green.

But beware: not all quality features are visible on the certificate!

• Shades & tints (brown, gray, green, blue) are often not listed. A stone with color undertones can be visually undesirable despite a good rating.
• Inclusions can reach the surface, which can affect the durability of the stone.
• Milky or blurred optics (“haze”, “graining”) are not always mentioned in the certificate, but can reduce the brilliance.

💡 Tip: An expert with experience can help to recognize genuine quality – just looking at the certificate is often not enough!

Lab diamonds have at least the same durability as mine diamonds, often they are even more compacted i.e. harder than mine diamonds and therefore even get the better durability.

Lab diamonds often have better color & clarity & hardness than mine diamonds

Although the FTC says diamonds are essentially pure carbon, the vast majority of mine diamonds contain trace amounts of other substances, notably nitrogen, which gives them a yellow color, or (rarely) boron, which gives them a blue color. In addition, they usually contain inclusions, tiny foreign bodies that were trapped in the still-forming diamond millions of years ago.

→ Lab diamonds therefore have often even a better color and purity (= quality). Partly Lab diamonds are even harder than mine diamonds because of a better “compression”. Nevertheless, inclusions also occur in lab diamonds. The inclusion types of lab diamonds are also found in mine diamonds. So they are not different/different types of inclusions. Only a few mine diamonds have so-called “natural inclusions”. Analogous to a mosquito in an amber. Such inclusions do not occur in lab diamonds in the “clean” lab environment.

Lab diamonds are made of crystallized carbon (pure carbon), which is also what mine diamonds are made of. In addition, Lab diamonds have the same atomic lattice structure (cubish).

Our lab diamonds have identical chemical, physical and optical properties.

What more could you want?
Same material, same atomic lattice structure – optically, chemically and physically identical!
