Lab Grown Diamonds Description


Diamond cultivation is a process of growing small diamonds.

(1) Derived from diamond seeds: in the laboratory, the use of advanced equipment and cutting-edge technology to restore the natural environment, the size of gravel or flake diamonds as seeds, into the culture chamber, to provide atomic structure template for the growth of diamonds;

(2) high temperature and high pressure environment: in the culture chamber, temperature and pressure will rise rapidly, high temperature and high pressure environment more than one hundred miles deep underground avenue, artificial creation of harsh natural diamond formation conditions;

(3) Through the carbon containing nutrients: graphite (C) or methane (CH4) will add the carbon source into the culture chamber, under high temperature and high pressure environment and special treatment, the chemical bond between the carbon atoms in the raw material will break, become free carbon atoms;

(4) Seed cultivation size: The free carbon atoms will be attracted by the nearby carbon atom structure, so they will gradually attach to the diamond seed, and combine with the carbon atoms of the diamond seed to form new chemical bonds, so that the seed will gradually grow up.
