CVD Single Crystal Diamonds Description
CVD (chemical vapor deposition) diamond, commonly known as single
crystal CVD diamond, is a kind of synthetic single crystal diamond.
It is a mixture of carbon containing gas and oxygen, which is
excited to decompose at high temperature and pressure lower than
the standard atmospheric pressure to form activated diamond
carbons, The polycrystalline diamond (or diamond single crystal or
quasi single crystal) is deposited on the substrate. Because CVD
diamond does not contain any metal catalyst, its thermal stability
is close to that of natural diamond. Like the Synthetic
Polycrystalline Diamond at high temperature and high pressure, the
CVD diamond grains are disordered and have no brittle cleavage
surface, so they are isotropic. CVD diamond is now used as a tool
material.
The high hardness and wear resistance of diamond make CVD diamond
an excellent tool material. Compared with PCD, this material has
the advantages of good thermal stability and long tool life. The
disadvantage is that the cohesive strength between grains is low,
and the material shows large internal stress and brittleness. In
addition, the lack of conductivity of CVD diamond hinders the
application of this material in EDM and polishing. The technology
has been widely used in diamond tool processing industry,
especially in the grinding and heavy grinding of wood tools.

CVD Single Crystal 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.
