What is lab created 钻石?
实验室培育钻石 are manufactured, diamond-like crystals.The manufacturing processes work to duplicate the pressure and temperature of the 天然钻石-producing environment.The formation process is initiated by forcing a chemical reaction, through adding a catalyst to carbon, and placing the mixture in high-pressure cells. Then, the mixture is cooled and washed with acid, which results in a 实验室培育钻石. Our method used in the production of 实验室培育钻石 is high pressure high temperature (HPHT) technology.
