Lab Grown Rough Diamonds Description
Diamond grown in laboratory is usually produced by chemical vapor deposition (CVD) or high pressure high temperature (HPHT).
High purity high temperature heat treatment (HPHT), which has been used since 1950s, places a pure solid carbon source under high pressure and high temperature. In the presence of catalyst, the carbon heated under pressure crystallizes into diamond. HPHT is sometimes used to improve the color of mined or laboratory grown diamonds.
Laboratory grown diamonds are man-made, like diamonds crystals.The The manufacturing process work replicates the pressure and temperature of the natural diamond production environment. By adding a catalyst to the carbon and placing the mixture in a high-voltage battery, the formation process is initiated by a forced chemical reaction. The mixture was then cooled and washed with acid to produce laboratory grown diamonds.
The quality of diamonds produced in the laboratory can range from lower than natural diamonds to higher than natural diamonds, depending on the technology and individual manufacturing processes.

Lab Grown Rough 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 Lab Grown Diamonds and natural diamonds?
There is no obvious difference between the 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.
