2021-2-21 · What is HTHP diamond? HPHT technology is to treat natural diamond with high temperature and pressure to improve the color grade of diamond. In terms of moving, it can be upgraded to 4-6 levels. However, not every diamond can be processed by this technology. It must have a J color or higher, contain no impurities, and have high quality.

2019-6-5 · The huge advantage of this method is that temperatures are lower – only around 800 degrees Celsius – and there is no longer a need for the intense pressures required by HPHT manufacturing. And CVD arguably works better: according to Arden Jeweler 'CVD diamonds can be grown over larger areas by starting with a larger diamond seed plate.

2021-11-22 · Unlike HPHT diamonds, CVD diamonds are less expensive to create because they only require moderate heat and far lower pressure. The creators can also control the color of the diamonds. Carbon and hydrogen create colorless crystals, while introducing other gases like boron can produce yellow or blue synthetic diamonds.
