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 (currently up to over 10 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.
