Where is the origin of jadeite? Where is the best jadeite?

The most important origin of jade is China's neighboring country, Myanmar. The main consumer and import country is China. The exact origin of jadeite rough is in the Mengong and Myitkyina areas of Myanmar, 150 kilometers away from Yunnan, my country.

my country has a history of four to five hundred years as a consumer of raw jadeite. Four to five hundred years ago, a large amount of raw jadeite was transported to China from its origin. The jadeite of "Dynasty Jadeite" passed through Tengchong, Yunnan. , Ruili and other border cities were imported into my country.

In addition to the raw jadeite produced in Myanmar, there are also small amounts of jadeite produced in places such as Central Kazakhstan, the Coastal Mountains of California, Guatemala, Mexico, and Honshu, Japan, but the quality and quantity cannot match that of jadeite. Myanmar jade comparison.

The best jadeite in the world is produced in Myanmar. It can be said that this country is the only place in the world that produces high-quality jadeite.

Burmese native jadeite, the top quality is produced in the Wulu River (a tributary of the Kindon River, also known as "Uyou River" and "Uyu River") in northern Myanmar. The mining area is distributed in the early third quarter metamorphic rock belt. The rocks that make up the metamorphic zone include serpentine, blue amphibole schist, actinolite schist, serpentinized dunite and chlorite schist, and these schists are cut through by granite veins in local areas. The jade veins are found in the serpentinite in the Dumao area. The jadeite ore body is vein-shaped and lens-shaped, forming a long and thick mineral zone. Burmese secondary jadeite is composed of jadeite gravel, which is distributed in the upper reaches of the Wulu River. High-quality jadeite gravel often has a fine-grained brown crust, which is an important symbol for distinguishing primary jadeite (mountain material) and secondary jadeite (seed material). . Myanmar's most famous jade mining area covers an area of ​​about 13 square kilometers and is only 150 kilometers away from the Yunnan border in China.
