“Radiant beauty, modern brilliance – your Radiant Cut diamond, the radiant masterpiece for timeless shine

King of white flashes and sparkle.
The radiant cut sparkles the most of all square cuts and can even compete with the brilliant. The Radiant cut combines the sparkle of the round brilliant diamond with the elegance of the emerald cut. The rounded corners make it less delicate than a Princess Cut. This not only ensures greater wearing comfort, but also a longer service life.

What makes the radiant cut so unique? What are the advantages of radiant grinding?

  • Modern: Radiant’s were invented in 1977 and are therefore the most modern diamond shape
  • Radiant cut is a beautifully symmetrical, non-traditional cut.
  • Radiant = Emerald + Brilliant: combination of “step cuts” (emerald shape) and “brilliant cuts” (round)
    → combines the brilliance of a round and the purity of an emerald cut
    → maximum brilliance (bright white flashes), sparkle and fire (rainbow-colored flashes)
    70 facets → one of the most brilliant diamond shapes
  • One of the Sparkliest Cut’s -> white sparkle
  • “Crushed Ice”: Radiant’s are shaped with many facets and angles, making them appear almost like crushed ice
  • Flaws and inclusions are easily concealed
  • Diagonal (corner to corner) can fool the eye and make it appear larger than a round brilliant of the same carat weight
  • Trimmed corners give it versatility to shine in all types of jewelry, especially engagement rings
  • Radiant Cut = first square cut diamond (the second is the princess), which has a full brilliant cut facet pattern on both the crown and pavilion, creating a vibrant and lively square diamond.
  • Durable: beveled corners add stability and make it a smart choice for people with active lifestyles

Recommendation for radiant cut diamonds: What should you look out for when buying a radiant cut diamond? What are the disadvantages of radiant grinding?

  • Well centered “Culet”
  • Parallel sides and corners ground to the same size
  • Avoid too big bowtie (black shadows through the middle)
  • slightly smaller face-up area, about 4% smaller -> rather take more Carat

Radiant cut diamonds are some of the most sparkling on the market. This diamond cut was invented in 1977 and is the most modern diamond shape. However, it can still look like a classic. Whether oblong or square, a radiant cut diamond will stand out from the crowd and give your ring a unique look.

Which stars and celebrities have a radiant cut diamond engagement ring?
Some celebrities who wear an engagement ring with a radiant-cut diamond are:

  1. Drew Barrymore: Drew Barrymore’s engagement ring from Will Kopelman is adorned with a radiant radiant-cut diamond.
  2. Jennifer Lopez: Ben Affleck gave Jennifer Lopez a stunning engagement ring with a radiant-cut diamond during their first engagement.
  3. Khloé Kardashian: Khloé Kardashian’s engagement ring from Lamar Odom featured a large radiant-cut diamond.
  4. Ivanka Trump: Her engagement ring from Jared Kushner contains a radiant radiant-cut diamond.

What is the difference between a round brilliant cut diamond and a radiant cut diamond?
The main difference between a round brilliant-cut diamond and a radiant-cut diamond lies in their shape and facet structures:

  1. Round diamond (brilliant cut):
    • Shape: The round diamond has a classic round shape and is the most commonly used cut.
    • Facets: The round brilliant cut has 57 to 58 facets, which are divided into different parts such as table, crown and pavilion. This faceted structure is designed to capture and reflect the light optimally, resulting in a brilliant sparkle.
  2. Radiant cut:
    • Shape: The radiant cut is generally rectangular or square with cut corners. It can also be considered a square brilliant.
    • Facets: Radiant diamonds can have different numbers of facets, but they usually have a higher number of facets compared to round brilliant diamonds. The arrangement of the facets should also create an impressive sparkle.

Compared to the classic round diamond, radiants have a slightly smaller surface area, around 4% smaller. However, the diagonal measurement of a radiant cut can fool the eye and make it appear larger than a round brilliant with the same carat weight.

Of all diamond shapes, round brilliant diamonds offer the most light reflection and sparkle. However, a radiant cut is one of the most brilliant cuts and will produce a very sparkling diamond.

Both cuts are known for their brilliance and sparkling beauty, but the choice between them often depends on the wearer’s personal preference. The round brilliant cut is timeless and traditional, while the radiant cut offers a modern touch with its more unusual shape.

What is the difference between a princess cut diamond and a radiant cut diamond?
Princess-cut and radiant-cut diamonds have different facet patterns, but the most obvious difference for the uninitiated is their shape. Princess cuts are square, while radiant cuts have beveled corners. These differences in shape not only affect the aesthetic appearance, but also the durability.

Princess cuts are known for their clean lines and distinctive square profile, while radiant cuts offer a rectangular or square brilliant pattern with their beveled corners. Here are some additional differences:

  1. Sparkle and brilliance:
    • Princess cuts tend to produce a sharper sparkle, while Radiant cuts offer a softer brilliance with wider light reflections.
  2. Number of facets:
    • Princess diamonds usually have a higher number of facets (usually 76), which can lead to a higher brilliance. Radiant diamonds tend to have fewer facets (usually 62-70), which can result in a bolder, multi-faceted appearance.
  3. Corners and durability:
    • The sharp corners of a princess cut could tear or chip more easily, while radiant cuts with their rounded corner structure can be considered more resistant.
  4. Style and versatility:
    • Princess cuts are often considered modern and contemporary, while radiant cuts offer versatility that suits both classic and modern designs.

Both cuts have their unique advantages, and the choice between a princess and a radiant cut often depends on personal preference, the desired appearance and style of the piece of jewelry.

What is the difference between a cushion-cut diamond and a radiant-cut diamond?
Cushion-cut diamonds are characterized by their gentle curvature, while radiant-cut diamonds have straight sides. These differences influence not only the aesthetic appearance, but also the visual effect and light refraction of the diamonds.

  1. Shape and contours:
    • Cushion cuts have a characteristic square or rectangular shape with rounded corners that lend a vintage aesthetic. In contrast, radiant cuts have beveled corners and offer a more modern, angular appearance. In a three-stone ring setting, the contours of radiants can be a great option to create a striking look.
  2. Fire and brilliance:
    • Cushion cuts tend to show more dispersion or fire, which manifests itself in flashes of colored light. This type of sparkle gives the diamond a special vibrancy and is well suited for those who prefer an eye-catching, colorful sparkle. In contrast, radiant cuts tend to create more white sparkle, resulting in an elegant and timeless appearance.
  3. Number of facets and light reflection:
    • Cushion diamonds usually have larger facets, which can lead to greater light reflection and a softer, gentler appearance. Radiant diamonds, on the other hand, often have smaller facets, which can lead to a bolder, multi-faceted appearance.
  4. Popularity and style suitability:
    • Cushion cuts are popular with lovers of vintage designs and go well with classic and romantic styles. Radiant cuts, on the other hand, are often seen as more versatile and suit both modern and classic designs.

Both cuts have their unique characteristics, and the decision between a Cushion and Radiant cut often depends on personal preference, the desired style and the desired visual effect.

What should I look for in a Radiant diamond shape?
Like other fancy gem cuts, radiants get their appeal mainly from their shape. Make sure that the corners are evenly blunted. Avoid contours with excessively cut corners, as they look misshapen. Always avoid radiant cut diamonds with unevenly cut corners.

What length width ratio should a Radiant cut diamond have?
Radiant cut diamonds come in a wide range of length-to-width (L/W) ratios. This is a matter of personal preference, but most consumers prefer an L/W of 1.15 to 1.35 for oblong shapes or below 1.05 for square radians.

Please also read «Bowtie effect (black shadow)» under Shapes and Ovals.

Do Radiant diamonds have a bowtie?
Like Ovals, Pear and Marquise cut diamonds, Radiant cut diamonds have a bowtie – a dark band in the center of the stone. Poorly cut diamonds show a dark loop, but a well-cut radiant still has good sparkle throughout the stone. Always look closely at this part of the diamond to make sure it sparkles well.

What should be the minimum color of a Radiant diamond?
Like other fancy shapes, radiant cut diamonds show more color than round brilliant diamonds. Nevertheless, an H- or I-colored radian will appear white in any ring setting. Some J and K color diamonds also look great. Lower color grades are perfect for setting the diamond in yellow or rose gold. Since the color of the metal is reflected in the diamond anyway, even the highest color grades (D, E & F) show a slight tint in these settings.

What should be the minimum clarity of a Radiant diamond?
Due to the intense brilliance or light return of a radiant cut diamond, inclusions are difficult to detect in a low clarity diamond. You can find eye clean diamonds in SI1 and SI2 clarity grades.

Always look for large, dark inclusions under the panel facet. These can be seen with the naked eye. SI1 not eye clean: With a large, dark inclusion in the center of the stone, an SI1 clarity diamond cannot be eye-clean.

For diamonds weighing two carats or more, you should also consider VS2 clarity. Since larger diamonds have inclusions more easily, you may need to opt for a higher clarity grade on a larger diamond to ensure it is eye clean.

What are the perfect dimensions for a Radiant Cut diamond? What mass should a Radiant diamond have in terms of depth and table? What is the ideal length ratio for a Radiant cut?

  • Depth 61-67%
  • Table 61-69%
  • Length-to-Width Ratio 1.15 to 1.35 for elongated shapes
    • Long ratios are currently particularly trendy for larger stones and give the Radiant Cut an elegant, slender, large look.
    • For small diamonds, for example 1 carat, a ratio of 1.40 or less is recommended as otherwise the stone becomes very thin and rice grain-like
  • Length-to-Width Ratio below 1.05 for square radians
  • Well centered “Culet”
  • Parallel sides and corners ground to the same size
  • Avoid too big bowtie (black shadows through the middle)

But there are also great diamonds outside of these areas. If you want to see more choices, expand your search parameters to a depth of 59-70% and a board of 58-71%.

We recommend using a little more Carat for Radiants, because the face-up surface is a little smaller.

Length-to-width ratio Radiant versus Emerald

With Radiant Cuts, the ratios are generally somewhat shorter than with Emerald Cuts, especially with the rectangular variants. While the Emerald Cut often has a ratio of 1.40 to 1.50, Radiant Cuts, especially in rectangular form, are often in the range of 1.10 to 1.30.

A longer ratio in a radiant cut can make the diamond look more oval or even emerald cut, whereas a shorter ratio will make the diamond appear more square and compact.

The ratio also influences how the diamond reacts to the light. With shorter ratios (for example 1.00 to 1.10), the radiant cut can show more sparkle and fire, while longer ratios (over 1.30) can make the diamond appear larger.

Do longer ratios have a greater effect?

Radiant cut diamonds with a higher length-to-width ratio (ratio) also appear larger. A longer ratio means that the diamond appears longer and narrower, which makes it visually larger, especially from a length perspective.

What does this mean for the purchase of a Radiant Cut diamond?

A radiant cut diamond with a longer ratio (e.g. 1.50 or higher) has a greater visual presence. The longer design makes the diamond appear larger overall, even though it doesn’t necessarily weigh more carats in reality. This is ideal for buyers who want a diamond that makes a bigger impression without requiring an overly large budget.

Advantages of a longer ratio with the Radiant Cut:

  • The diamond appears larger and has a noble, stretching effect.
  • The longer cut offers an elegant, modern look.
  • Particularly advantageous for people with narrower fingers or for those who prefer a longer diamond.

Tip for buyers: If you opt for a radiant cut diamond with a longer ratio, make sure that the symmetry and proportions of the diamond are well balanced. A well-proportioned radiant cut diamond offers a nice balance between size and brilliance without making the diamond look too narrow or long.

Buy cheap radiant diamonds? How can I save money on a Radiant Cut Diamond?
Radiant cut diamonds hide inclusions well, so a clarity grade of SI1 or SI2 still looks beautiful! With a color grade of H, you get the most bang for your buck with a white gold setting, but with rose gold or yellow gold, you can go down to a color grade of I.

The Radiant Cut combines the best of both worlds: the brilliance of a brilliant cut diamond with the elegant shape of an emerald cut. Anyone looking for a radiant Radiant Cut Diamond at the best price should follow these tips:

Lab Grown Diamonds 💰 – The biggest saving! Lab-grown diamonds are up to 70% cheaper than mine-grown diamonds, with identical beauty & quality.

✔ O ptimize length-to-width ratio 📐 –
1.00 – 1.20 (square/slightly rectangular) – Classic, balanced, maximum sparkle.
1.25 – 1.35 (Elongated Radiant) – Stretches the finger & appears visually larger.
A good cut is crucial ✨ – Radiant cuts with excellent symmetry & proportions maximize the play of light and make the stone appear larger & more brilliant.

Note the choice of color 🎨 – Radiant diamonds show color more strongly than round brilliants, but less than cushion or emerald cuts.
Mine diamonds: G-H still looks colorless in white gold & platinum.
Lab diamonds: F may already be brownish, so better choose E or D if a cool, white stone is desired.
VS1 or better at Lab Diamonds 🔍 – Mine diamonds often look flawless in VS2 or SI1, but VS1 is worthwhile for lab diamonds as the price difference to VS2 is minimal.

✔ Narrower ring shank for greater effect 💍 – A thin ring shank or halo makes the stone appear larger without costing more carat.

💡 Extra tip:
If you want the best sparkle and brilliance, you should opt for an excellently cut radiant with good symmetry and proportions.

Conclusion: Radiant Diamonds are perfect for anyone who loves maximum brilliance & an elegant shape – with these tricks you get the best look at the best price! 😊💎

When was the Radiant cut diamond invented? What is the story, the history of the Radiant Cut diamond?
The Radiant Cut was created in 1977 by Henry Grossbard of the Radiant Cut Diamond Company to maximize brilliance (bright white flashes), sparkle and fire (rainbow-colored flashes).
In many painstaking and costly experiments, Henry sought to give the elegant but glassy emerald cut shape the brilliance and sparkle that make diamonds so special, creating the Radiant Cut in 1977. His breakthrough revolutionized the industry, and an era of creativity and excellence in diamond cutting followed.
