What's Synthetic diamond?
A synthetic diamond (also known as a laboratory-grown diamond, a cultured diamond, or a cultivated diamond) is a diamond produced by a controlled process, as contrasted with a natural diamond created by geological processes or an imitation diamond made of non-diamond material that appears similar to a diamond. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively). While the term synthetic may sometimes be associated by consumers with imitation products, synthetic diamonds are made of the same material as natural diamonds—pure carbon, crystallized in an isotropic 3D form.
What Are CVD Diamonds?
A CVD or Chemical Vapor Deposition Diamond, also referred as a laboratory-created Diamond, is produced by means of a synthetic method, as compared to real or Natural Diamonds, which are generated by physical processes. In addition, CVD Diamonds started appearing in the gemstone Diamond market many years ago. This process involved bringing a gas like methane into a vacuum chamber and then activating and breaking down the molecules of the gas with microwaves, which causes the carbon atoms to accumulate on a substrate like the way snowflakes accumulate in a snowfall.
What are the Methods to create the CVD Diamonds?
There are now mainly two methods of manufacturing CVD Diamonds, the first is the HPHT or High Pressure High Temperature process and the other is CVD or Chemical Vapor Deposition. The HPHT method was used to successfully grow Diamonds in 1956 by General Electric, and basically mimics the natural process. The HPHT process and the energy and equipment needed is costly and produces Diamonds with mostly brownish or yellowish colors. On the other hand, using the CVD process is inexpensive because it works at moderate temperatures with a low pressure that needs smaller and less costly tools. Colorless crystals can be grown as the vacuum chamber contains mainly carbon and some hydrogen. Yellow or Blue CVD Diamond crystals can be produced if boron or nitrogen is introduced into the chamber.
