VS+ Clarity GH Color Artificial White CVD Diamond Synthetic Diamonds For Sale In China
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 composed of 10 to 30 nm in diameter diamond crystallization aggregation of crystal diamond, more early artificial diamond with nitrogen from the air atom into diamond crystals and light color syrup, after scientists improved production methods, production of synthetic diamond and natural diamond without any differences in appearance.
Because of 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 synthetic diamond production technology, its cost is low, and can be made into a variety of colors of diamonds and jewelry market. While synthetic diamonds have been produced in laboratories and factories for decades, gem-quality synthetic diamonds have only recently emerged. Originally, man-made diamonds were mainly used for industrial purposes such as making cutting tools, as well as for jewelry.

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 diamond identification require specialized appraisal organization and appraisal instrument can be realized, and as a result of the design technology and equipment capital is very high, 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.
