What is CVD/HTHP diamond?
It uses graphite or diamond powder, or a mixture of graphite and diamond powder as a carbon source, and dissolves them in an iron-nickel alloy catalyst. The dissolved carbon in the catalyst enters the high-pressure chamber by the temperature gradient of the high-temperature and ultra-high pressure reaction chamber. Precipitated and grown gem-grade diamond on lower diamond seed crystals. Colorless, yellow, green and blue varieties have been synthesized, most of which are yellow.
