Lab Created Diamonds Description

Synthetic diamond cultivation methods mainly include HPHT high pressure and high temperature method and CVD chemical vapor deposition method, and the cultivation time is about half a month to one month. 1) HPHT high pressure and high temperature method: Pure toner is compressed into a growth capsule and then placed in a culture chamber. At extremely high temperature (up to 1300-1600°C) and pressure, carbon atoms are joined together to form diamond crystals. It takes about two weeks to grow large diamond rough particles of more than 10 carats. 2) CVD chemical vapor deposition method: a diamond sheet is placed in a hollow chamber, which is filled with a mixture of hydrogen and methane and heated to vaporization under a specific pressure. Carbon atoms are deposited layer by layer on the sheet to form a uniform diamond coating. It takes nearly a month to grow a cut 1-carat CVD diamond crystal.
