GH VS SI 0.01ct 0.02ct Synthetic Melee Diamonds For Diamond Earrings
Synthetic Melee Diamonds Description
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.
Lab grown diamonds is usually produced by chemical vapor deposition (CVD) or high pressure high temperature (HPHT).
Perhaps the oldest way to make diamonds is through a high-pressure,
high-temperature process. Since the mid-1950s, laboratory diamonds
have become part of the market through this technology.
General Electric first introduced this method, which follows the
natural process of diamond creation. It imitates the process of
making natural diamonds. It involves using pressure and heat to
crystallize carbon deep in the earth.
Laboratory grown diamonds can also come from the CVD process. CVD
represents chemical vapor deposition.
CVD diamonds come from various gases, such as methane. They are
stored in a vacuum chamber, which decomposes the molecules of the
gas, and then these molecules gather on the pre-existing diamond
seeds.

Synthetic Melee 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.
