CMC chief executive technical consultant Mills purchased a 2.62 kt pendant shaped bright yellow diamonds, asking $ 22,000. Mills diamond from the laboratory, the same weight, the price may be higher mining diamonds from the ground thousands of dollars.

glass diamond only a small portion of the $ 80 billion global diamond market, but demand is increasing, because the buyer wants to buy cheaper diamonds, and freedom from moral flaws. "Blood diamonds" from the term is used to remind lead to conflict diamonds in Africa to enhance the role.




According to the survey, 18 to 35-year-old North American consumers, only 45% prefer natural diamonds. Including Wal-Mart, Helzberg diamond shops and other businesses, have been launched to purchase synthetic diamonds. It is estimated that the production of synthetic diamonds last year only 360,000 karats, but natural diamonds mined in 2013 was 146 million karats. 2018, the laboratory glass diamond may supply up to 200 million carats in 2026 amounted to 20 million carats.

This in the lab "to develop" synthetic gemstone, physical characteristics and chemical structures and real plastic crystals is no different. Production method is to seed carbon methane or another carbon-containing gas into a microwave chamber, ultra-high temperature heating become hot plasma ball, after the formation of crystalline diamond particles produced, the process takes about ten weeks. Current manufacturing technology, has reached the expert level must be the instrument can tell the difference between a real diamond.

The world's largest plastic crystals producer laboratory IIA Singapore Technologies Inc., 3.04-carat synthetic diamond asking for $ 23,000, the same weight, the same level of real diamond, the price is about $ 40,000.
