Lab Grown Diamond HPHT/CVD - synthetic gems
Lab Grown Diamond HPHT/CVD. Lab grown diamonds are generally produced by chemical vapor deposition (CVD) or high pressure high temperature (HPHT) methods. CVD uses ultra-pure carbon-rich gases in a controlled environment. It produces Type IIa diamonds, which are quite rare in nature and account for less than two percent of all mined diamonds.

Lab Grown Diamonds – The Synthetic vs Natural Battle of 2020
Given what you've read thus far, you might be wondering whether lab-grown diamonds diamonds have the same chemical, physical, and optical properties as natural diamonds mined from the ground. That's because you've been led to believe that natural and synthetic diamonds are the same thing by the marketing gurus hired by people who sell lab-grown

be CVD or HPHT synthetic diamonds. Inscription. Major HPHT synthetic manufacturers often inscribe the origin on the girdle (e.g., “Lab Grown” or other wording). However, the lack of an inscription does not necessarily indicate a natural stone, as diamonds can be recut or a manufacturer might not inscribe the syn-thetic origin. Advanced Testing.

Synthetic diamond (also referred to as laboratory-grown diamond, laboratory-created diamond, or cultured diamond) is a diamond made of the same material as natural diamonds: pure carbon, crystallized in an isotropic 3D form. Synthetic diamonds are different from both natural diamond, which is created by geological processes, and diamond simulant, which is made of non-diamond material.
