Lab Grown Polished Melee Diamonds Description
Laboratory-grown diamonds have many different names-laboratory diamonds, laboratory-made diamonds, laboratory synthetic diamonds, and even synthetic diamonds. These names indicate that cultivated diamonds are artificially created in laboratories or factories, rather than naturally formed or mined from the ground. The laboratory cultivating 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 laboratory diamonds from natural diamonds. The physical and chemical properties of laboratory-grown diamonds and natural diamonds are exactly the same as those of natural diamonds.
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.

Lab Grown Polished 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.
