The 30/35 coarse grain diamond produced by Henan Nanyang Zhongnan Diamond Co., Ltd. has recently obtained the national approval certificate. The advent and mass production of this product indicates that the history of China's history of not producing coarse-grain high-grade diamonds has been rewritten, and China's diamond synthesis technology has reached the world's advanced level. Henan Nanyang Zhongnan Company has synthesized a coarse-grain high-grade diamond single crystal which can only be mass-produced by foreign two-side presses on the domestic six-face press. The cost is only one quarter of the cost of similar foreign products.
