Dr. Yuan talks about diamonds: the first stage of a technological breakthrough in CVD growth to nurture diamonds has been successful
The successful definition of the first stage of CVD growth cultivation of diamonds is the simultaneous growth of: 1, positive white color, using a 2-inch tray reactor. 2,SI1 above the clarity. 3, grow the largest number of diamonds. 4, each seed crystal can be expanded in the growth of 1~2mm diameter.
This first stage breakthrough will reduce the growth cost by 1/2 to 2/3. Therefore, CVD cultivated diamonds have the potential to be reduced to the Lightbox retail price of De Beers. Bare stone 1 karat J/VS2,US$800/carat, which translates into Rapaport quotation US$5300/carat, which is about 15%. Different weight, color, clarity of the naked stone, according to the quotation of 15% as the retail price, wholesale price for about half of the retail price, all other operators have to pay more than the Lightbox certificate fee. At present, the cost of GIA and IGI's diamond cultivation certificates is too high. In the future, we will strive for their price reduction.
The Lightbox retail price of US$800/carat was calculated by De Beers after careful consideration and actuarial calculation. We should not lower the standard according to this standard. We hope all operators will maintain this standard for a long time. In the future, when the quality and price of diamonds are mature, there is still 10 to 100 times the demand space for jewelry use. I hope all CVD manufacturers will not focus only on jewelry use.
The definition of success in the second stage of technological breakthrough in CVD growth and diamond cultivation is to expand the tray of CVD reactor to 4 inches and 6 inches, and to 8 inches and 12 inches in the future.
CVD cultivated diamonds in many industries, will be the ultimate material for a long time.

Dr. Yuan Zhizhong, Chairman of Bench Diamond Technology, gave a lecture entitled "Identification of Gem Diamonds Cultivated by CVD Method" at the Appraisal Institute on the 11.9 at the invitation of the Appraisal Institute of Taiwan Gemological Institute. In the lecture, Yuan Dong introduced in detail the historical principles of CVD diamonds and their development status, and introduced in detail several methods to distinguish CVD diamonds from natural diamonds on how to identify gem-grade CVD diamonds that participants are concerned about! Yuan Dong's wonderful speech was well received by the participants!
Dr. Yuan Zhizhong, Chairman of Bench Diamond Technology, was invited by Hangzhou International Jewelry City to attend an academic symposium on November 19, 2013. At the symposium, Yuan Dong gave a speech entitled "International Situation and Identification of CVD Synthetic Diamonds" on the current situation of CVD synthetic diamonds that jewelers are concerned about and how to distinguish CVD diamonds from natural diamonds. In the speech, Yuan Dong introduced in detail the history of CVD diamonds, the international situation of CVD diamonds and the commonly used identification methods of CVD diamonds, and answered some questions raised by jewelers. Mr. Yuen's speech was well received by the participants, and all jewelers said they benefited.
