    CVD Lab Grown Diamonds Description


    Laboratory diamonds, also known as lab grown diamonds, man made diamonds and synthetic diamonds. At present, there are two main methods to create lab grown diamonds: HPHT(High Temperature and High Pressure) method and CVD(Chemical Vapor Deposition)method.

    Both natural diamond and lab grown diamonds are pure carbon crystals, and their physical, chemical, crystal structure and optical properties are same. Due to the different formation conditions, the nature of natural diamonds and cultivated diamonds are also different. However, natural diamonds grow into octahedral crystals (eight equilateral triangular facets), while cultivated diamonds can grow into both octahedral and cubic crystals (six square facets).

    HPHT stands for High Pressure High Temperature Method, which is a main method used in laboratories to make diamonds. This diamond growth process requires carbon to be exposed to extreme temperature and pressure conditions, which simulate the extreme heat and pressure conditions when natural diamonds are formed in the depths of the earth.

    High temperature and high pressure synthetic diamond technology originated in the 1950s, initially mainly used in aviation and military industry, in the last decade has achieved a qualitative leap in technology, gem grade synthetic diamond in quality and cost has reached the level of marketization.

    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 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.
