Artificial Lab Created Diamonds Description
CVD stands for chemical vapor precipitation, another method for making diamonds in the laboratory. The growth of such diamonds requires the application of the appropriate pressure and temperature to the hydrocarbon mixture in a vacuum chamber.
Artificial diamond is a kind of diamond crystal polymer from 10 to 30 nanometres in diameter, the early artificial diamond due to the nitrogen atoms in the air into the diamond crystal and light sugar thin color, after scientists improve the production method, the production of artificial diamond in appearance and natural diamonds have no difference.
Because of the different natural environment, artificial diamond of molecular structure is not completely octahedral structure of natural diamond but a complex structure, which can produce phosphorescence. With the mature of synthetic diamond production technology, and its low cost, and can produce all sorts of color of diamonds in ZhuBao field. While synthetic diamonds have been produced in laboratories and factories for decades, gem-quality synthetic diamonds have only recently emerged. Originally artificial diamond is mainly used for manufacturing cutting tools and other industrial USES, also be used in jewelry.
China's CVD cultivated diamond is also one of the world's diamond producers. With the continuous improvement of domestic consumers' awareness of cultivated diamond, the demand of the international market is increasing, so the demand of cultivated diamond market is gradually increasing.

Artificial Lab Created Diamonds Introduction
CVD foster mother is in accordance with a natural diamond drill gia is stone, with high purity, methane in hydrogen, nitrogen and other gases, in the microwave in high way, let the methane and diamond like carbon molecules constantly accumulated to the original stone diamonds, through layers of hyperplasia, this method can produce 10 carat transparent diamond, methane as carbon source, So a diamond grown this way is indistinguishable from a natural diamond. The naked eye cannot tell the difference.
With the continuous improvement of science and technology, the diamond produced by CVD method can meet the 4C standard.
Like the HPHT diamond manufacturing process, the CVD manufacturing process is improving, allowing manufacturers to create larger stones with greater color and clarity.
Artificial diamonds are indistinguishable from natural diamonds in their fine appearance.The identification of synthetic diamonds requires specialized identification institutions and identification instruments. Due to the high cost of design technology and equipment, only a few laboratories in the world have the ability to identify synthetic diamonds and natural diamonds. The international identification institutions of synthetic diamonds are IGI International Gemological Institute and GIA American Gemological Institute.
