About Lab Grown Diamond
Lab Grown diamonds, also known as synthetic diamonds, are generated in the laboratory, and humans use advanced technology and equipment to reduce the high-temperature and high-pressure environment formed by natural diamonds in the laboratory, and the use of small diamond crystals to induce natural diamonds Crystallize, in order to grow diamonds on the surface with the physical, chemical and optical properties of natural diamonds are exactly the same.
There are two main manufacturing methods for lab diamonds, one is the high temperature and high pressure method (HPHT Lab Grown Diamond), and the other is the chemical vapor precipitation method (CVD Lab Grown Diamond )
HPHT Lab Grown Diamonmd
1. From diamond seeds: In the laboratory, the use of advanced equipment and cutting-edge technology to restore the natural environment, the grit size or flake diamond as a seed, placed in the culture bin, to provide an atomic structure template for the growth of diamonds;
2.high temperature and high pressure environment: in the incubator, the temperature and pressure will rise rapidly, and the high temperature and high pressure environment at the depth of the road more than 100 kilometers will artificially create harsh formation conditions for natural diamonds;
CVD Lab Grown Diamonmd
CVD lab diamonds are created by igniting methane gas in a container and depositing carbon in a high temperature and pressure environment that mimics natural diamonds in high-tech instruments
