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 lab grown 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.
After polished, the Lab Grown HPHT diamond can be applied as a gemstone alternate to natural diamonds for jewelry decoration and production. its hardness is 10 moh's almost same as natural diamond.
They never lose their their shine or color and are also cut and polished in the same way as mined diamond ,they have the same lustre and fire as the mined diamonds .
