Lab Grown 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, cultured 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 the cultivation of 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.

From a scientific point of view, cultivated diamonds are exactly the same as natural diamonds, the only difference being where they are formed.
Prospects And Advantages Of Lab Grown Diamonds
Henan's diamond cultivation industry chain is the largest and most mature in the world. Demand for growing diamonds remains high in the global market, especially in the United States. The Indian factory, located in the diamond processing sector, has bought up almost all of the rough breeding diamonds and is still unable to meet orders. In the field of superhard materials, the growth potential of gemstone grade products is huge and will continue to be in short supply for the foreseeable future. The entire cultivation diamond market is in its early stage of development, and the global demand for synthetic diamonds has not really started to grow in the domestic market except the US market.
