Zveřejněno na podle Kingjy

The sapphires produced in Penglai, Hainan Province and Mingxi, Fujian Province are beautiful in color and transparent. Crystals with a particle size less than 5mm have fewer internal defects, while larger ones have more cracks.

The sapphires produced in Heilongjiang Province are bright and transparent, but have fine particles. Although some products in Jiangsu Province are beautiful and transparent, they often have cracks and are difficult to process and obtain materials. The sapphire (the largest one weighing 54. 27ct) produced in the placer of Liuhe County in the province cannot be used directly because of the deep color. ; But there are cracks, processing and retrieving is difficult; the sapphire produced in the placer of Liuhe County (the largest one weighs 54. 27ct) cannot be used directly because of the deep color; but the successful color change experience, quality and The economic efficiency is significantly improved.

Navíc, sapphire origins have been found in southwest Anhui Province, southern Jilin Province, northeastern Liaoning Province, and Qushui County in Tibet.

Similar to the situation around the world, China has fewer rubies than sapphires. So far, only four rubies with industrial value have been discovered in Wenchang County, Hainan Province (discovered in 1978), southwestern Anhui Province (discovered in 1981), eastern Heilongjiang Province (discovered in 1986), and Ailao Mountain in Yunnan Province. .

Obecně, the reserves and exploitation of gem-grade rubies and sapphires in my country are not large. Dnes, most of the red sapphires on the jewelry market in my country are imported, especially the large and beautiful ones.
