Nanhong, the full name of Nanhong Agate, is a general term for a kind of red agate produced in southwest China, which is colorful, moist and full of vitality. It is a kind of jade material with thousands of years of application history. The ancients called agate red Qiong (red Qiong originally meant ruby). The output of south red agate, which can reach the standard of bright color and few cracks, has been very low, and the royal family and Buddhists in China have been obsessed with collecting south red. 0 1 it is said that the south red agate was mined and disappeared during the Qianlong period of the Qing dynasty, and now it has spread from the Han dynasty to the south red agate of the Ming dynasty. Nanhong, a new mine, is mainly produced in Liangshan, southern Sichuan, and also produced in Baoshan, Yunnan. However, there is no gem-grade ore in Baoshan, which is mainly produced in Liangshan Yi Autonomous Prefecture, Sichuan. Nanhong is named after being produced in southern China, including Yunnan, southern Sichuan, Qinghai and Gansu. Nanhong has long been exploited and utilized by people. Some people say that the so-called "red jade" in ancient books is a guide to red agate. South red agate is bright in color, delicate in texture and very beautiful. It first appeared in the Warring States Period. Nanhong is precious because of its natural red color. In addition, the scarcity of materials and extremely low output also make Nanhong even rarer.
