Round Brilliant Cut Synthetic HPHT White Lab Grown CVD Diamond
Lab grown HPHT diaimond are manufactured, diamond-like crystals.The manufacturing processes work to duplicate the pressure and temperature of the natural diamond-producing environment. The formation process is initiated by forcing a chemical reaction, through adding a catalyst to carbon, and placing the mixture in high-pressure cells. Then, the mixture is cooled and washed with acid, which results in a synthetic HPHT diamond.
Quality of lab grwon HPHT diamonds can vary from inferior to superior to the natural diamond, depending upon the technology and individual manufacturing processes. The methods used in the production of synthetic diamonds are high pressure high temperature (HPHT)
