CVD Lab Grown Diamonds Description
The laboratory grown diamonds are diamonds grown in the laboratory.
The diamond layer is synthesized by growing natural or artificial
diamonds as seed crystals and simulates the growth environment of
natural diamonds.
Natural diamonds and man-made diamonds are pure carbon crystals,
and their crystal structure, physical properties, chemical
properties and optical properties are same.
Are lab grown diamonds real diamonds?
The diamond industry often uses these analogies to answer this
question: Lab grown diamonds and natural diamonds are like the
relationship between greenhouse flowers and natural flowers. They
are all flowers, but they grow in different environments. Lab
diamonds and natural diamonds are like ice in a refrigerator and
ice in nature. They are all ice, but the formation environment is
different.
Synthetic diamonds, also known as laboratory grown diamonds,
cultivated diamonds or cultivated diamonds. Unlike natural diamonds
formed by geological processes or imitation diamonds made of
non-diamond materials that are similar in appearance to diamonds,
synthetic diamonds are diamonds produced through a controlled
process.
Synthetic diamond production methods include HPHT diamond (high
pressure and high temperature) method or CVD diamond (chemical
vapor deposition) method.

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.
