CVD Diamond Description


Lab-grown diamonds, as the name suggests, are diamonds made in a laboratory.
Many people may think that because they are grown in a laboratory, they are all artificial diamonds and fake diamonds. In fact, making lab diamonds just uses high technology to simulate the environment in which diamonds are formed in the earth's crust, and then accumulate carbon atoms layer by layer to form rough stones. The rough stone is no different from the original diamond dug from the ground.

There is almost no difference between lab grown diamonds and natural diamond. lab grown diamonds and natural diamond both are real diamond. But strictly speaking, lab grown diamonds and natural diamond have different nitrogen content. The main difference between lab grown diamonds and natural diamond is that nitrogen exists in different forms.

The production process of lab grown diamonds has been very advanced, even experts need to use special equipment to distinguish them. The structure of man-made diamond is not the complete octahedral structure of natural diamond, but a complex structure.

In July 2018, in the latest jewelry guide, the US Federal Trade Commission revised the definition of diamond, which has been used for 62 years, and deleted the word "natural". This shows that people's recognition and acceptance of synthetic diamonds undoubtedly greatly encouraged the synthetic diamond market.

CVD Diamond​ 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.
