Certified Lab Grown Diamonds Description
Diamonds are famous all over the world as luxury and precious jewelry. Lab Grown Diamonds grow above the earth in a diamond lab and unlike mined diamonds; there is no excavation and mining hence keeping nature and natural resources intact. This contributes in green environments.Laboratory diamonds are a type of diamond quality obtained by chemical vapor deposition (CVD) or high temperature and high pressure (HPHT).
HPHT is the primary method used to grow rough diamonds in a laboratory. At present, the world's popular high-temperature and high-pressure synthetic diamond equipment mainly includes two side top, six side top and bar split sphere or improved split sphere.
CVD diamonds are grown in a vacuum chamber filled with a mixture of hydrocarbons (such as methane). An energy source (such as a microwave beam) breaks down the gas molecules, and the carbon atoms are adsorbed down to the flat diamond seeding disk at a lower temperature
In order to make CVD diamond grow smoothly, methane with diamond structure is often used as carbon source. Methane can be regarded as a monatomic diamond pressed out by hydrogen. The quality of lab diamonds is almost the same as that of natural diamond, which is hard to distinguish with the naked eye.
For consumers, a professional diamond certificate can clearly show the detailed characteristics of the diamond. So that people can clearly know the quality of the diamonds they buy.

Certified 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 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.
