The technology at Heyaru is duplicated to recreate the exact conditions vital to grow a natural diamond not under, but above the surface of Earth. These grown diamonds are created using Chemical Vapour Deposition (CVD) method.
Chemical Vapour Deposition (CVD):
The chemical vapour disposition method can grow diamonds in labs with this simple yet expensive technology. More complicated and expensive than the HPHT method, the CVD works at lower pressures exposing multiple diamond seeds to a carbon rich environment. Under favourable conditions, carbon starts depositing, while the diamond seeds accept the available carbon and thus the process of crystallization starts naturally.
