CVD Lab Grown Diamonds Description
Are the rough diamonds grown in the laboratory real diamonds?
The rough diamonds grown in the laboratory and the natural diamonds
grown in the laboratory are pure carbon and have the same physical
and chemical properties.
What is the difference between a lab-grown rough diamond and a
natural diamond?
Both natural and laboratory-grown rough diamonds are produced with
carbon components, which are transformed into scintillating cubic
crystals. Although its chemical basis provides laboratories with
the same optical properties as natural diamonds, the cultivation of
laboratory diamonds is not inherently rare. Natural diamonds are
formed by squeezing deep layers of the earth's crust. This is why
all natural diamonds that will always exist are "produced" and make
them rare in the world. In turn, the laboratory will grow diamonds,
and the production of diamonds is unlimited.
Artificial diamonds are often called Lab Grown Diamonds, which is
produced by simulating the crystallization process of natural
diamonds. When natural diamonds are formed in natural environment,
there are often other elements mixed in, which makes some natural
diamonds not completely transparent and will show specific colors.
For example, some diamonds have a little pink, some with a little
blue, some with a little bit of light yellow. Lab Grown Raw HPHT
Diamonds grow in the laboratory, which are less impurities than
natural diamonds, so the purity and transparency will be higher.

CVD Lab Grown 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.
