There are two main ways to produce a Lab Grown diamond. The first is a process called HPHT (High Pressure High Heat) and the second is CVD (Chemical Vapour Disposition) HPHT diamonds are produced in an environment of extreme heat and pressure conductive to diamond growth. CVD diamonds often begin life as a HPHT produced diamond seed which is ...
Lab-grown diamond: Natural diamond: At $2,260, the lab grown diamond is $3,140 less expensive than the natural diamond. It is priced at 42% of the price of the natural stone. 1 carat is a popular weight for diamonds, so there is a lot of supply at this size.
Cost of HPHT and CVD Diamond Manufacturing. Lab grown diamonds can be manufactured via HPHT (High Pressure High Temperature) process or by CVD (Chemical Vapor Deposition) process.. HPHT mirrors the natural diamond growing process. This process was developed in the 1950s to grow genuine diamonds in a controlled environment.
