Jade production and trade in Myanmar : ウィキペディア英語版 | Jade production and trade in Myanmar
Jade production and trade in Myanmar refers to the mining, distribution, and manufacture of the variety of jade called jadeite, which is produced in the nation of Myanmar (formerly known as Burma). Most of the jadeite mined in Myanmar is not cut for use in Myanmar; instead, it is exported to other nations, primarily in Asia, for use in jewelry and other products. The jadeite deposits found in Myanmar's northern regions are the highest quality jadeite in the world, considered precious by sources in China as far back as the 13th century. Today, it is estimated that Myanmar provides upwards of 70 percent of the world's supply of high quality jadeite.〔Hughes, Richard W. (2000) ("Burmese Jade: The Inscrutable Gem, Part I: Burma's Jade Mines" ) Pala International〕 == Geography of jade deposits ==
Jadeite in Myanmar is primarily found in the "Jade Track" located in the upper Myanmar Kachin State which encompasses the alluvial region of the Uyu River between the 25th and 26th parallels. Extraction of jade in this region is concentrated particularly in the towns of Tawmao, Hpakan, Hweka and Mamon with Hpakan having developed as the present-day center of jade mining since the Malaysian government's loosening of restrictions on gemstone mining in 1995. In addition to this region, there are also notable mines in the towns of Nasibon and Natmaw in the neighboring Hkamti District.〔〔("2001 Gem News Archive: Oct. 29, 2001: New Burma Jade Mine" ) ''Gem News'' Pala International〕
