Loose Lab Grown Diamonds Description
The lab grown diamonds uses advanced technology to simulate the
formation conditions of natural diamonds under the earth's crust.
This formation process is the main factor that distinguishes
lab-created diamonds from mined diamonds. Lab-grown rough diamonds
are synthesized in a few weeks, while the development of natural
diamonds takes billions of years.
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.
Although laboratory-grown diamonds are formed in different
environments and conditions from natural diamonds, both natural
diamonds and cultivated diamonds are crystals composed of pure
carbon, and the physical properties, chemical properties, crystal
structure and optical properties of the two are the same.
Lab grown diamonds is usually produced by chemical vapor deposition
(CVD) or high pressure high temperature (HPHT) methods.
Can we distinguish between laboratory grown diamonds and natural
diamonds?
Yes it is. However, only diamond professionals can identify the
difference between laboratory grown diamonds and natural diamonds
by using professional diamond identification equipment.

Loose 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.
