CVD Lab Grown Diamonds Description
Diamonds are made of pure carbon in the shape of a tetrahedron.
Diamonds are famous all over the world as luxury and precious
jewelry. However, it is also the hardest substance in nature, a
good heat conductor and an inert substance. These characteristics
mean that diamonds can play an important role in some industrial
applications, such as metal cutting, drilling, grinding, mining and
construction, as well as applications in high-pressure testing and
high-performance bearings.
For a long time, people believed that diamonds could only be
"man-made" under high pressure and high temperature conditions,
imitating the formation of natural diamonds. The use of this method
to make diamonds is now very common, mainly for the aforementioned
industrial applications. However, in the late 1980s, scientists
discovered how to use a method called chemical vapor deposition
(CVD) to "plant" diamonds.
Diamonds produced by CVD are produced by mixing hydrocarbons,
usually methane, with hydrogen in a low-pressure vacuum chamber.
The diamond will grow in a few days until it reaches the size
required for the specific application. This process requires a
constant, stable and reliable source of hydrogen, which makes
Peak's hydrogen generator an ideal solution.
Normally, when methane and hydrogen are mixed, carbon is produced
in a non-diamond form, such as graphite. In the CVD chamber,
microwave energy, electric discharge, or hot cathode is used to
generate hydrogen atoms, which react with non-diamond carbon to
form vapor. Highly active hydrocarbon vapors will further react
with hydrogen atoms, resulting in the separation of hydrogen and
pure carbon, and pure carbon is deposited as diamonds. With the
repetition of this process, the diamond can grow into different
sizes according to the required application.

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.
