Cultivating the present and future of 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.
Now cultivated diamonds account for the global diamond market.5%However, 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, so there is still a lot of market space for cultivated diamonds, plusCVDThe private use of diamonds in industry will gradually develop and mature in the next few years, and the demand will be for jewelry diamonds.10~Hundred times share.
