CVD Diamond Description
Lab-grown diamonds, as the name suggests, are diamonds made in a
laboratory.
Many people may think that because they are grown in a laboratory,
they are all artificial diamonds and fake diamonds. In fact, making
lab diamonds just uses high technology to simulate the environment
in which diamonds are formed in the earth's crust, and then
accumulate carbon atoms layer by layer to form rough stones. The
rough stone is no different from the original diamond dug from the
ground.
There is almost no difference between lab grown diamonds and
natural diamond. lab grown diamonds and natural diamond both are
real diamond. But strictly speaking, lab grown diamonds and natural
diamond have different nitrogen content. The main difference
between lab grown diamonds and natural diamond is that nitrogen
exists in different forms.
The production process of lab grown diamonds has been very
advanced, even experts need to use special equipment to distinguish
them. The structure of man-made diamond is not the complete
octahedral structure of natural diamond, but a complex structure.
In July 2018, in the latest jewelry guide, the US Federal Trade
Commission revised the definition of diamond, which has been used
for 62 years, and deleted the word "natural". This shows that
people's recognition and acceptance of synthetic diamonds
undoubtedly greatly encouraged the synthetic diamond market.

CVD Diamond Introduction
Natural diamonds are created by nature and are the result of high
temperature and pressure formed over billions of years. The 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 Lab Grown Diamonds and natural
diamonds?
There is no obvious difference between the 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.
