Dr. Yuan on Diamonds: The Price of Cultivating Diamonds
The color of the cultivated diamond is an important factor affecting the price, which is divided into two categories: the white system and the system with brown and gray-black secondary colors.

Dr. Yuan talks about diamonds: the present and future of cultivating diamonds
In recent years, the diamond market of cultivated diamonds in the world has become more and more prosperous, especially in the United States, which is the most mature, and Eurasia and other regions have gradually followed up. At present, cultivated diamonds account for about 5% of the global diamond market, but the market is in a state of short supply, especially for white diamonds above 1 karat. Natural diamond mines will gradually dry up, and the main mineral deposits will have more than ten years of life left. The supply gap of natural diamonds in the market will gradually be filled by cultivated diamonds. Therefore, there is still a large market space for cultivated diamonds. In addition, CVD diamonds will be gradually developed and matured in the past few years, and the demand will be 10-100 times the share of jewelry diamonds.
