Man-Made Colored Diamonds Description
What are CVD and HTHP diamond?
Laboratory diamond is also widely known as high temperature and
high pressure diamond or chemical vapor deposition diamond. CVD and
HPHT are two common production methods. It refers to high pressure
and high temperature method and chemical vapor deposition method
respectively. In the high temperature and high pressure method, the
purest carbon is sent to the laboratory in the same environment to
convert it into diamond; In chemical vapor deposition, diamond is
formed atom by atom.
The difference between natural diamonds and laboratory diamonds
cannot be distinguished by the naked eye. Only trained gemologists
can find the difference by using special equipment. The price
difference between natural diamonds and laboratory diamonds is
between 30% and 70%. The diamonds produced in the laboratory are
cheaper, and the purity can be controlled manually, so the quality
is usually better.
There is a general misconception that the quality of diamonds
produced in laboratories is poor, but with advanced technology, the
quality of diamonds produced is usually better than that of
diamonds mined. Due to the difference in price and superior
quality, laboratory diamonds are more and more accepted by people,
especially the younger generation.

Man-Made Colored Diamonds Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The Rough
Lab Grown Diamonds are produced in the laboratory, usually in a few
weeks. The chemical difference between the two is same.
So how do you distinguish between Rough Lab Grown Diamonds and
natural diamonds?
There is no obvious difference between the Rough Lab Grown Diamonds
and natural diamonds. Even professional gemologists need special
equipment to identify them. By zooming in, professionals will be
able to discern subtle contrasts in diamond inclusions grown and
mined in the laboratory.
