    Lab Grown Rough Diamonds Description


    Lab Grown Diamonds, also known as man made diamonds, cultured diamonds and lab created diamonds, are grown in a highly controlled laboratory environment using advanced technology, which reproduces the natural conditions for the formation of diamonds under the mantle and crust. These synthetic diamonds are made up of actual carbon atoms, which are arranged in the unique crystal structure of diamonds. Because they are made of the same material as natural diamonds, they have the same optical and chemical properties.

    HTHP and CVD are the two main methods for making laboratory-grown diamonds.
    High temperature and high pressure method (HTHP) uses graphite as raw material, introduces suitable metal catalysts, such as Fe, Co, Ni, Mn, Cr, etc., and can synthesize diamond at temperatures above 2000K and tens of thousands of atmospheres.
    CVD stands for chemical vapor deposition, which is another method of making diamonds in the laboratory. The growth of this kind of diamond requires proper pressure and temperature of the hydrocarbon gas mixture in the vacuum chamber. Like the HPHT diamond manufacturing method, the CVD manufacturing method is constantly improving, allowing manufacturers to create larger gems with greater improvements in color and clarity.

    Lab Grown Rough 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.
