Man-Made Colored Diamonds Description


What are CVD and HTHP diamond?
Laboratory diamond is also widely known as high temperature and high pressure diamond or chemical vapor deposition diamond. CVD and HPHT are two common production methods. It refers to high pressure and high temperature method and chemical vapor deposition method respectively. In the high temperature and high pressure method, the purest carbon is sent to the laboratory in the same environment to convert it into diamond; In chemical vapor deposition, diamond is formed atom by atom.
The difference between natural diamonds and laboratory diamonds cannot be distinguished by the naked eye. Only trained gemologists can find the difference by using special equipment. The price difference between natural diamonds and laboratory diamonds is between 30% and 70%. The diamonds produced in the laboratory are cheaper, and the purity can be controlled manually, so the quality is usually better.
There is a general misconception that the quality of diamonds produced in laboratories is poor, but with advanced technology, the quality of diamonds produced is usually better than that of diamonds mined. Due to the difference in price and superior quality, laboratory diamonds are more and more accepted by people, especially the younger generation.

Man-Made Colored 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.
