What is CVD/HTHP diamond?
Synthetic diamond is also widely known as HTHP diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively). Under HTHP method, purest carbon is given the same environment into the lab so that it can convert into the diamond and in CVD method , the atmosphere is created which leads to atom by atom formation of diamond .

5.Q: What gives moissanite its fire?
A: A gemstone's fire is determined by a gemological property called dispersion. Moissanite's dispersion is 0.104, which exceeds that of any gemstone, including diamond, ruby, sapphire and emerald.
6.Q: Will moissanite fade or change color over time?
A: No. There are no likely situations in which the color of moissanite will be permanently changed. Moissanite does undergo a temporary color change when exposed to extreme heat from a jeweler's torch during jewelry repair, but with proper bench techniques there will be no lasting damage, and the stone will return to its normal color once it cools.
7.Q: Is moissanite resistant to scratching?
A: Yes. Moissanite is durable, tough and extremely resistant to scratching and abrasion. With a hardness of 9.25, moissanite is harder than all other gemstones except diamond.
