Loose Diamond
Rough Lab Grown Diamonds Description
Although laboratory-grown diamonds are formed in different
environments and conditions from natural diamonds, both natural
diamonds and lab diamonds are crystals composed of pure carbon, and
the physical properties, chemical properties, crystal structure and
optical properties of the two are same. Lab rough diamonds are
grown in the laboratory by imitating the high temperature and high
pressure environment of diamonds deep in the earth.
Due to the different growth environments of laboratory-grown
diamonds and natural diamonds, the shape, clarity and color of the
diamond will be different, so the price will also be different.
However, the price of lab grown diamonds is still relatively low
compared to mined diamonds.
Natural diamonds are usually formed millions even billions of years
ago, 160 kilometers or more deep underground, and were brought to
the surface in volcanic eruptions many years later. Since the
formation conditions of natural diamonds are very strict and the
formation period is also very long, natural diamonds are perfectly
octahedrons.
Because the laboratory environment species currently cannot reach
the ultra-high temperature required for the formation of natural
diamonds, and the cultivation time is relatively short, synthetic
diamonds often exhibit octahedral and cubic shapes.
At present, there are two main methods for cultivating diamonds in
the laboratory, namely, high temperature and high pressure method
and chemical vapor deposition method. Both of these mainstream
methods are currently in mass production. Because the two methods
use completely different equipment and manufacturing principles,
the laboratory-grown diamonds produced by the two methods are
completely different in shape.
Whether laboratory-grown diamonds or natural diamonds, loose
diamonds after cutting and polishing can not be distinguished by
the naked eye. It can be detected only with the help of
professional equipment.

Rough 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 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.
