Recently, the scale, production capacity and quality of China's diamond cultivation industry have reached the world's highest level, and the output of almost 80% of the world's total.

What is growing a diamond? The experiment is to lab created diamond is artificial diamond, is the scientists through the simulation of the growth environment of natural diamond, through very precise instruments, in a short time (one to three weeks or so) to cultivate the diamond with the same carbon elements arrangement structure of natural diamond.
The research of this technology has a history of 70 or 80 years. Through the continuous efforts of scientists, the diamond of gemstone machine has been cultivated successfully in recent years. Because there is no essential difference between lab grown diamond and natural diamond, the price is much cheaper, so it is rapidly favored by female consumers in developed countries such as Europe, Japan and South Korea.

It has the same physical, chemical and optical properties as natural diamond, and the hardness is 10. There is no such thing as genuine or fake diamonds. As long as there is reasonable public disclosure of the sale of lab created diamonds, lab created diamonds are a segment that can reasonably exist in the market. At present the international academic circle all affirms it is to have the diamond that wears value.

Artificial breed diamond, a lot of people are not very understand, actually artificial breed diamond is in the laboratory "plant" diamond, in recent years "plant" the diamond purity that comes out is higher and higher, already enough rival natural diamond.
