Lab Grown Diamonds Description


Lab grown diamond is to artificially simulate the formation conditions of natural diamond, so that the carbon of non-diamond structure is transformed into the carbon of diamond structure. To put it simply, the raw material of graphite powder is transformed into diamond structure through high temperature and high pressure processing.
There are two main processes used to produce lab grown diamonds: high pressure and high temperature (HPHT) and chemical vapor precipitation (CVD). Since 1950, the high pressure and high temperature method was used for the first time to successfully synthesize diamonds, and now the main countries that use this technology to manufacture gem-grade synthetic diamonds are China, Russia, the United States and so on.
