Lab Grown Diamonds Description
Diamond cultivation is a process of growing small diamonds.
(1) Derived from diamond seeds: in the laboratory, the use of advanced equipment and cutting-edge technology to restore the natural environment, the size of gravel or flake diamonds as seeds, into the culture chamber, to provide atomic structure template for the growth of diamonds;
(2) high temperature and high pressure environment: in the culture chamber, temperature and pressure will rise rapidly, high temperature and high pressure environment more than one hundred miles deep underground avenue, artificial creation of harsh natural diamond formation conditions;
(3) Through the carbon containing nutrients: graphite (C) or methane (CH4) will add the carbon source into the culture chamber, under high temperature and high pressure environment and special treatment, the chemical bond between the carbon atoms in the raw material will break, become free carbon atoms;
(4) Seed cultivation size: The free carbon atoms will be attracted by the nearby carbon atom structure, so they will gradually attach to the diamond seed, and combine with the carbon atoms of the diamond seed to form new chemical bonds, so that the seed will gradually grow up.

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
In recent years, diamond cultivation in the global diamond market is more and more prosperous, especially the Most mature market in the United States, Eurasia and other regions are also gradually follow. Cultivated diamonds now account for about 10% of the global diamond market, but the market is in short supply, especially for white diamonds of more than one carat. Natural diamond mines will be dried up, the main mineral deposits left more than a decade of life, natural diamond supply on the market will gradually by cultivating diamond are available, so cultivating diamonds have great market space, coupled with the CVD diamond folk USES in the industry, will gradually mature development over the last few years, demand for jewellery diamond 10 ~ one hundred times.
