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.
