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
