Lab Created Diamonds Description
Laboratory-grown diamond, or cultured diamond for short, is a
synthetic diamond grown in a Laboratory to mimic the natural
formation conditions of natural diamonds. Lab-grown diamond and
natural diamond in physical, chemical, optical properties are
completely consistent, all belong to the real diamond. The
mainstream imitation diamond products on the market, such as zircon
and Mosang, are mainly composed of zirconia and silicon carbide,
respectively, which are different from the pure carbon content of
diamonds.
The synthetic methods of diamond cultivation mainly include
high-temperature and high-temperature method (HTHP method) and
Chemical Vapor Deposition method (CVD method). HPHT high pressure
and high temperature method is to take graphite and diamond powder
as carbon source, in the hexahedral high pressure machine, simulate
the growth environment of natural diamond (temperature 1400-1700
degrees Celsius, pressure 5.2-5.6GP) so that carbon atoms and
carbon atoms are connected together to form diamond crystals. In
CVD chemical vapor deposition method, diamond flakes are put into a
vacuum chamber, which is filled with a mixture of hydrogen and
methane, heated to gasification under a specific pressure to
decompose methane, and carbon atoms are deposited layer by layer on
the flakes to form a uniform diamond coating.
Lab created diamond is also known as synthetic diamond, artificial
diamond, is produced in the laboratory of diamond, and natural
diamond physical, chemical properties are completely the same, at
the same time compared to natural diamond cost-effective. Many
consumers are curious about the new category of lab grown diamond.
In the past, CCTV Finance has also repeatedly reported lab created
diamond related topics, giving affirmation to the cultivation of
diamond market.

From a scientific point of view, cultivated diamonds are exactly
the same as natural diamonds, the only difference being where they
are formed.
