Qinghai Kunlun Jade Yuhuan Kunlun Jade, also known as Qinghai nephrite, is produced in Yuxufeng, the birthplace of Taoism at the southern foot of Kunlun Mountain under the jurisdiction of Golmud City, Qinghai Province, with an average elevation of more than 4,200 meters. Its main component is a fibrous microcrystalline combination composed of translucent stone and actinolite, which belongs to the same metallogenic belt as Hetian jade in Xinjiang. Although it was only discovered in the 1990s that the mining time was only twenty years, in just a few years, Kunlun jade has established its position as one of the four nephrite producing areas in China and one of the main white jade producing areas in China with excellent quality and abundant reserves.
Yuhuan used for Olympic medals: sapphire and sapphire Kunlun jade are white jade, sapphire, topaz, jet, emerald and other varieties, which are highly engravable, delicate and soft in texture, elegant and refreshing, oily and obviously more transparent than Hetian jade, and are recognized as high-quality gems in the international jewelry industry at present. Kunlun jade can stand out from many varieties and become a jade material inlaid with gold and jade cards, which is inseparable from its characteristics. Qinghai Kunlun jade has short mining time, large reserves and many bulk materials, which can meet the needs of using the same materials for the same medal and provide sufficient raw materials for the medal making of Beijing Olympic Games. Moreover, Kunlun jade is rich in color, and it is easy to distinguish the grades of gold, silver and bronze. On June 2, 2008, it was officially identified as the jade for medals in Beijing Olympic Games.
