CVD Lab Grown Diamonds Description
Lab created diamonds are grown by simulating the growth environment
of natural diamonds through high temperature and high pressure or
chemical vapor deposition method. The chemical, physical, atomic,
and optical properties of lab grown diamonds are the same as
natural diamonds. we call them laboratory-grown diamonds.
CVD (Chemical Vapor Deposition) diamond is based on a loose natural
diamond stone as the parent stone, using high-purity methane, plus
hydrogen, nitrogen and other gases to assist, in a microwave oven
at high pressure to make methane the same carbon as diamonds
Molecules continue to accumulate on the rough diamond, and after a
layer of proliferation, a transparent diamond as large as 10 carats
can be formed.
Another method is HPHT(high temperature and high pressure), which
uses metal elements as catalysts to simulate the temperature and
pressure environment produced by natural diamonds for lab grown
diamond growth.
As the first generation of diamond growth technology, high
temperature and high pressure technology can completely simulate
the growth process of natural diamonds, reproduce the reaction of
the carbon layer on the ground, and convert graphite into diamonds.
At present, the popular high temperature and high pressure
synthetic diamond equipment in the world mainly includes two side
tops, six side tops and strip split ball or improved split ball.

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 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.
