Uncut 6ct HPHT Rough Diamond Lab Grown DEF Color VS Clarity For Rings
Uncut White DEF Color VVS VS SI Clarity HPHT Rough Diamond For Rings
Lab Grown Diamonds Description
Artificial diamond is a diameter of 10 to 30 nanometers of diamond crystals from the aggregation of multi-crystal diamond, the early artificial diamond due to nitrogen atoms in the air into the diamond crystal and light sugar thin color, after the scientists improved production method, the production of artificial diamond in the appearance and natural diamond without any difference.
Due to the different natural environment, 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 artificial diamond production technology, its low cost, and can produce a variety of colors of diamonds and in the jewelry market. While synthetic diamonds from laboratories and factories have been around for decades, synthetic diamonds of gem-quality have only recently emerged. Synthetic diamonds were originally used for industrial purposes such as making cutting tools, but they are also used in jewelry.

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.
1. Laboratory-grown diamonds have the same physical, chemical and optical properties as natural diamonds
To simulate the growth environment of natural diamond, the diamond can be completely consistent with natural diamond in physical, chemical and optical properties only after a few weeks in the laboratory.
2. The birth of diamond cultivation has a long history. In recent years, attention has been continuously increased, and the concept and standard have been gradually clarified
