CVD Lab Grown Diamonds Description


Are the rough diamonds grown in the laboratory real diamonds?
The rough diamonds grown in the laboratory and the natural diamonds grown in the laboratory are pure carbon and have the same physical and chemical properties.

What is the difference between a lab-grown rough diamond and a natural diamond?

Both natural and laboratory-grown rough diamonds are produced with carbon components, which are transformed into scintillating cubic crystals. Although its chemical basis provides laboratories with the same optical properties as natural diamonds, the cultivation of laboratory diamonds is not inherently rare. Natural diamonds are formed by squeezing deep layers of the earth's crust. This is why all natural diamonds that will always exist are "produced" and make them rare in the world. In turn, the laboratory will grow diamonds, and the production of diamonds is unlimited.

Artificial diamonds are often called Lab Grown Diamonds, which is produced by simulating the crystallization process of natural diamonds. When natural diamonds are formed in natural environment, there are often other elements mixed in, which makes some natural diamonds not completely transparent and will show specific colors. For example, some diamonds have a little pink, some with a little blue, some with a little bit of light yellow. Lab Grown Raw HPHT Diamonds grow in the laboratory, which are less impurities than natural diamonds, so the purity and transparency will be higher.

CVD 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 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.
