Full White Lab Grown Diamonds Fancy Cut Loose Diamond For Ring
Lab Grown Loose Diamonds Description
Laboratory diamond is a diamond cultivated by machine in the laboratory. After polishing and cutting, laboratory grown diamonds are no different from natural diamonds. The diamonds produced in the laboratory and natural diamonds are real diamonds. The main chemical composition of diamonds and natural diamonds produced in the laboratory is carbon.
At present, high temperature and high pressure method and chemical vapor deposition method are two main methods to prepare laboratory diamond.
HPHT and CVD can produce laboratory diamond through laboratory diamond forming machine. However, due to the different machines and technologies used in the production of diamonds by HPHT and CVD, people can distinguish the diamonds produced by HPHT and CVD from those produced in the laboratory.
Fundamentally speaking, artificial diamonds and natural diamonds have basically the same physical properties, chemical composition and crystal structure as natural diamonds. It can not be called fake diamond, but the cultivation "growth" trajectory of diamond and natural diamond is different. They are honed after hundreds of millions of years, and the other is to simulate the growth environment of natural diamond and grow in a few months.
Characteristics Of Lab Grown Diamonds

From a scientific point of view, synthetic diamonds are identical to natural diamonds, the only difference being where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
In recent years, the diamond growing more and more prosperous in the global diamond market, particularly in the United States the most mature market, Eurasia areas also gradually follow up. Artificial cultivation of diamond currently accounts for about 10% of the world diamond market, but the market demand, especially in more than one carat of white diamonds. Natural diamond mine will be exhausted, the main mineral resources still have more than ten years of life, the supply of natural diamond on the market will gradually be obtained by the cultivation of diamonds, so there is a lot of market space to cultivate diamonds, coupled with CVD diamond in the civil use of the industry, in recent years will gradually mature development, jewelry diamond demand for 10 ~ 100 times.
