NowGIA,IGIThe cost of certificates for diamond cultivation is too high. We will fight for their price reduction in the future.
LightboxThe retail priceUS$800/Carat, De Beers came after careful consideration and actuarial calculation. We should not lower the standard according to this standard. We hope that all operators will maintain this standard for a long time. In the future, when the quality and price of cultivated diamonds are mature, there will be 10 to 100 times the demand space for jewelry use. I hope allCVDThe industry should not focus only on the use of jewelry.

CVD cultivated diamonds in many industries, will be the ultimate material for a long time.
