Lab Created Diamonds Description
Cultured diamond was born in the laboratory, as a high-tech "blessing" products, in physical, chemical, optical properties and natural diamond completely consistent. At present, the main synthetic methods of diamond cultivation are high pressure and high temperature method (HPHT) and chemical vapor deposition (CVD), and the preparation time only needs half a month to a month.
