Lab Grown Diamonds Description


A kind of real diamond, obtained through technology.
Lab grown diamond growth principle: similar to the nature of fruit growth. In the process of growth, carbon atoms are constantly transformed into their own "tissue", and over time grow into a gem-grade diamond, that is, to complete the mission of growth.
Lab grown diamond and mining diamond difference: access to different sources, the naked eye can not distinguish, professional identification instruments can see the diamond growth pattern is different; Its chemical elements and light effect, hardness and other physical effects of mining diamond consistent, authoritative identification agencies can issue a certificate.
Common Lab grown diamond methods: HPHT (high temperature and high pressure) and CVD (chemical vapor deposition)
The basic principle of CVD chemical vapor deposition method: The free carbon is separated from the gas containing carbon element in a relatively low temperature and low pressure environment, and the carbon atom will continuously deposit and fall on the diamond seed, gradually deposition and growth, and grow into a diamond.

From a scientific point of view, lab grown diamonds are exactly the same as natural diamonds, the only difference being where they are formed.


Prospects And Advantages Of Lab Grown Diamonds


On the supply side, both artificially Lab grown rough diamonds and naked diamonds are in short supply globally. Most of China's artificially lab grown rough diamonds are exported to India, while most of the naked diamonds are exported to Europe, the United States, the Middle East and Southeast Asia. In terms of the terminal market, the European and American consumer markets are relatively mature, while the domestic market is in the growth stage and has a large market space.

Demand for lab grown diamonds is in short supply, and the market will improve as consumers embrace synthetic diamonds.
