Artificial Lab Created Diamonds Description
Lab-grown gemstones are designed by engineers to master the chemical composition, physical properties and natural origin of natural gemstones through analysis, and to simulate the natural forming environment of natural gemstones in the laboratory so as to breed gemstones with the exact same composition and characteristics as natural gemstones.
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, 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.
There are two ways to cultivate gem-grade diamonds in circulation :HPHT and CVD. HPHT (high temperature and high pressure) treatment can be used in the jewelry industry due to the large amount of impurities, but mostly in the industrial field. However, CVD (chemical deposition) treatment method has low yield and great technical difficulty, but its quality is generally good, which is widely used in the gem industry. In diamond classification, type ⅱ A diamond, is recognized, ideal and irreplaceable for ultra-precision machining tool, is also a very good optical window material, infrared optical window material, and a very advantageous semiconductor material. In nature, type II A diamonds only account for 2% of the total, but CVD diamonds are all type ⅱ A diamond, therefore,CVD diamond in the industrial field is mostly used in machinery, manufacturing, military, aerospace, science and technology, medical equipment and other high-tech fields, because of the excellent thermal conductivity of diamonds, so there will be great development in the chip field in the future, such as CVD diamond can be grafted with GN, improve the chip heat dissipation ability.
