Artificial Lab Created Diamonds Description
 
Diamonds are simply pure carbon bound together extremely tightly. Since then, researchers around the world have been pouring in the hope of building similarly compact structures in the lab.
As many people know, diamonds are extremely pure carbon. Graphite, too, is pure carbon, but because graphite's carbon atoms are loose, diamond's atoms are very tightly packed, which gives diamonds not only their chemical stability, but their physical strength.
There are two main types of gem-grade synthetic diamonds:
1. HTHP synthetic diamond (static pressure method)
HTHP synthetic method is mainly produced by BARS press. This method has low cost and small volume, but only one diamond can be synthesized at a time. Most high temperature and high pressure synthetic diamond to yellow, brown, low price, more as a substitute for natural color diamond.
2. CVD synthetic diamond (Chemical vapor precipitation)
CVD diamond synthesis technology appeared in 1952, there are many specific chemical methods, such as plasma method, hot wire method and other chemical methods. CVD diamond technology is also becoming more mature, producing diamonds that are difficult to identify with the naked eye.
