The molecular structure of lab grown diamond is not the complete octahedral structure of natural diamond but a complex structure, which will produce phosphorescence phenomenon.
The molecular structure of artificial diamond is not the complete octahedral structure of natural diamond but a complex structure, which will produce phosphorescence phenomenon. With the maturity of lab grown diamonds production technology, its low cost, and can produce a variety of colors of diamonds and in the jewelry market.

From a scientific point of view, they have the same physical composition, chemical properties, optical characteristics, even the authoritative gem appraisal agency has certified, of course, is the same, if there is anything different between the two, it is only the place of birth is different. For example, all people are born differently. Why look down upon others?
There is natural diamond is but a serious damage to the earth's surface bad environment, the cruel labor exploitation of the people of backward Countries in Africa, the endless harm caused by armed conflict, and finally the expensive stone monopolized by the diamond company marketing, and the cultivation of diamond is the light of human wisdom, the beauty created by science and technology.
Natural mining diamond contains impurities, in fact, color, purity is not much, so high grade can sell sky-high prices, but the basic cultivation drill is 2a type, is the top2% of the advanced category of diamond, cultivation drill cost is several times lower than natural diamond.
