Dr. Yuan talks about diamonds: the cutting and grinding of cultivated diamonds
The cutting and grinding of cultivated diamonds is basically similar to the cutting and grinding of natural diamonds. Most of the major producing countries of natural diamonds stipulate that diamonds dug up in the country must be processed into finished diamonds in the country before they are allowed to be exported, which can increase their employment opportunities and increase the value of diamonds. A fairly high percentage of cultivated diamonds are produced in China, and we can target large-grain cultivated diamond blanks and stay in China for cutting and grinding, thus increasing the value of cultivated diamonds.
