Lab grown HPHT diamond 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.
