The technology at Heyaru is duplicated to recreate the exact conditions that are vital in growing a natural diamond, not under, but above the Earth’s surface. These grown diamonds are created using the Chemical Vapour Deposition (CVD) method.

Chemical Vapour Deposition (CVD):

The Chemical Vapour Deposition method can grow diamonds in labs with simple yet expensive technology. More complicated and expensive than the HPHT method, the CVD method works at lower pressures that expose multiple diamond seeds to a carbon-rich environment. Under favorable conditions, carbon starts depositing, while the diamond seeds accept the available carbon and thus the process of crystallization starts naturally.
