In Yunnan are several centers for cutting but the mineral also were sent to Canton, Shanghai, and elsewhere to manufacture products and other objects out of it.
The value depended, just as today, upon color, translucency, and texture. The best is a uniform glassy emerald green color also named imperial jade.
Less valuable are other colors, all are manufactured into hi priced jewellery such as rings, necklaces, pendants and more.
Jadeite with less value is used for buttons, figurines, and drinking cups. Other are even used for plates, spoons, flowerpots, and cups, white material is often used for a Jade Buddha.
Until recently jade mining was under control of Chinese and Shan people, the material is mainly cut in Mandalay but the biggest jade market is in Yangon, that is
Bogyoke Aung San Market and during the Yangon Emporium.
Jade mining in Kachin State
is not so easy because there is still some fighting between the military the Kachin Independence Army (KIA) and the military. Although Kachin State has the biggest deposits of quality Jadeite they still keep on fighting since decades instead of sitting together make peace and give everyone the possibility to benefit from the rich underground.
The type of rough jade found in the region consist of alluvium, Uru boulder conglomerates, cenozoic sandstones, surpentinized peridotite and schists.
Jade dykes are found in the surpentinized peridotite while jade boulders occur in Uru boulder conglomerates that has been deposited in the Uru river valley.
