Lab grown HPHT/CVD 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/CVD 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) OR Chemical Deposition Method
Polished diamond applications:
polished lab grown HPHT/CVD loose diamond are usually applied as a gemstone alternate to natural diamonds for jewelry decoration and production. its hardness is 10 moh's almost same as natural diamond.

CVD Lab Created Diamond is cut and polished in the same manner as natural diamond, at the same cost. The stones can be laser inscribed on the girdle to allow easy preliminary identification. Figure 2 shows typical CVD-grown cut and polished Lab Created Diamond.
