White Hpht Rough Lab Grown Diamonds Description


Laboratory diamonds, known as synthetic diamonds. At present, there are two methods of artificial cultivation of diamonds in the world: high temperature and high pressure method and chemical vapor deposition method. These two kinds of diamond production methods are different, the products are the same, known as artificial cultivation diamond.


Are Lab Grown Diamonds the real diamonds?
Both the Lab Grown Diamonds and natural diamond cultivated in the laboratory are pure carbon, which are in the same cubic crystal form. Professionals can identify the differences between laboratory diamond and natural diamond through high-tech equipment, but it can't be done with naked eyes.


High pressure high pressure (HPHT) imitates the formation process of natural diamond, puts seeds under great mechanical pressure, and exerts great pressure and high temperature on ready-made carbon. Seeds will quickly turn into diamonds with carbon lattice and grow layer by layer in a few days until they reach the desired carat weight.

White Hpht Rough 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.
