CVD Lab Grown Diamonds Description
What is lab grown diamond?
Lab-grown diamonds are grown in the laboratory. People use advanced
equipment to simulate the environment in which natural diamonds are
formed.
This formation process is the main factor that distinguishes
lab-created diamonds from mined diamonds. Lab-grown diamonds can be
mass-produced within a few weeks. As a result, laboratory-grown
diamonds are much cheaper than natural diamonds of the same size
and quantity.
Since the physical and chemical properties of laboratory-grown
diamonds and natural diamonds are exactly the same as those of
natural diamonds, can one distinguish between the two?
The answer is yes. In fact, in terms of shape, rough lab created
diamonds and natural diamonds usually present different shapes. Due
to different formation conditions, natural diamonds usually present
octahedral crystals, that is, eight equilateral triangular crystal
faces, while cultivated diamonds usually grow into crystals that
contain both octahedrons and cubes, that is, six square crystal
faces. Therefore, it can be easily distinguished from the
appearance.
At present, there are two main methods for cultivating diamonds in
the laboratory, namely, high temperature and high pressure method
and chemical vapor deposition synthesis method. Both of these
mainstream methods are currently in mass production.
The synthetic diamond is the product of the development of high
technology. Synthetic diamonds is more environmentally friendly and
saves labor costs.

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.
