Jade, also known as jadeite, jadeite and Burmese jade, is a kind of jade. The correct definition of jadeite is fibrous aggregate composed of pyroxene minerals, mainly jadeite minerals, but jadeite is not equal to jadeite. Jadeite is a polycrystalline aggregate of stones that reaches the jade level under geological action. It is mainly composed of jadeite or jadeite, sodium (sodalite) and sodalite (omphacite), and may contain amphibole, feldspar, chromite and limonite.
In ancient times, jade was a bird that lived in the south. Its coat color is very beautiful, usually blue, green, red and brown. Generally, the male of this bird is red and called "Fei", and the female is green and called "Cui". "Tengyue Local Records" written by Inch Kaitai records: "Tengyue was collected by jade workers, made into utensils and sold in Yunnan and Chongqing provinces. Top grade jadeite is mostly sent to eastern Guangdong, Shanghai, Fujian, Zhejiang and Kyoto. By the end of the Qing Dynasty and the beginning of the Republic of China, there were more than 100 jade workshops and more than 3,000 jade carving craftsmen in Tengchong alone.
Emerald producing area
Meng Gong and Myitkyina in Myanmar, which produce jadeite, are only150km away from the Yunnan border in China. During the Wanli period of the Ming Dynasty, this place was once under the jurisdiction of Yongchang Prefecture (now Baoshan City, Yunnan Province). Due to historical reasons, jadeite, known as the "Oriental Treasure", was imported into China through border cities such as Tengchong and Ruili. There are several theories about the origin of the name of jadeite. In ancient China, Jade was a bird that lived in the south. Its coat color was very beautiful, usually blue, green, red and brown.
Generally, the male of this bird is red and called "Fei", and the female is green and called "Cui". The word "flying, red-feathered finch and green-feathered finch" is included in the earliest dictionary compiled by Xu Shen in the Eastern Han Dynasty, which refers to a bird in Lingnan area. Emerald has a long history. Emerald belongs to pyroxene, monoclinic system and two groups of perfect cleavage. The main component is sodium aluminosilicate NaAl9, and only if the gemstone contains more than 50% sodium aluminosilicate can it be regarded as jadeite.
