Today, it is estimated that Burma is the origin of upwards of 70 percent of the world's supply of high-quality jadeite. Most of the jadeite mined in Burma is not cut for use in Burma, instead being transported to other nations, primarily in Asia, for use in jewelry and other products. The jadeite deposits found in Kachinland, in Burma’s northern regions is the highest quality jadeite in the world, considered precious by sources in China going as far back as the 10th century.
Jadeite in Burma is primarily found in the "Jade Tract" located in Lonkin Township in Kachin State in northern Burma which encompasses the alluvial region of the Uyu River between the 25th and 26th parallels. Present-day extraction of jade in this region occurs at the Phakant-gyi, Maw Se Za, Tin Tin, and Khansee mines. Khansee is also the only mine that produces Maw Sit Sit, a type of jade. Mines at Tawmao and Hweka are mostly exhausted. From to 1964 to 1981, mining was exclusively an enterprise of the Myanmar government. In 1981, 1985, and 1995, the Gemstone laws were modified to allow increasing private enterprise. In addition to this region, there are also notable mines in the neighboring Sagaing District, near the towns of Nasibon and Natmaw and Hkamti. Sagaing is a district in Myanmar proper, not a part of the ethic Kachin State.
