Lab Created Diamonds Description
In fact, lab-grown diamonds are also known as synthetic diamonds, which are currently artificially grown by high pressure and high temperature and precipitation methods. Its growth concept is to use small diamonds as "seeds", through technical means to simulate the growth environment of natural diamonds, so that the carbon atoms in the "food" gradually adhere to the diamond seeds, so that the diamond seeds grow into larger diamond crystals.
Basically speaking, lab grown diamond and natural diamond have basically the same physical properties, chemical composition and crystal structure as natural diamond. It can not be called a fake diamond, but lab grown diamonds and natural diamond "growth" trajectory, environment is different, they are one after hundreds of millions of years of time to hone and become, the other is to simulate the growth of natural diamond environment, with a few months to grow.
Lab grown diamond now have two kinds, one is CVD synthetic diamond, this method is a chemical gas phase precipitation method, this method is now a mainstream, can be very two, mature production technology, to produce a synthetic diamond quality is high, is a kind of high temperature and high pressure synthesis of diamond, is to use principle of simulated diamond growth environment of high temperature and high pressure synthesis of diamond, can also produce high quality diamond, Relatively speaking, the method of high temperature and high pressure is not as easy as the CVD method. There are two methods, but it cannot be said that the synthetic diamond produced by that method is good. Both methods can synthesize high-quality synthetic diamond, and finally, synthetic diamond grading will be carried out.
