Certified Lab Grown Diamonds Description


Diamonds are made of pure carbon in the shape of a tetrahedron. 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.
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 (chemical vapor deposition) diamond is based on a natural bare diamond. With the assistance of high-purity methane, hydrogen, nitrogen and other gases, the carbon molecules in methane and diamond are continuously accumulated on the original diamond in a high-pressure way in a microwave oven. Every few days, the diamond is taken out, the top surface of the diamond is polished, and the non-diamond carbon elements are removed from it, and then returned to the growth chamber. Each batch of diamonds may need to go through several start/stop cycles, and the entire growth process takes three to four weeks. 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.
