Jade from Burma
The only other abundant source of good jade for the use of Chinese carvers was Burma. This jade was not discovered until the thirteenth century and took until the eighteenth to get to China, whose master carvers very likely were puzzled by its properties. It didn’t work like the stone they knew. It had a different set of characteristics and very different colors. However, it was jade and highly acceptable jade, at that. The long-delayed arrival of jadeite into China had finally come about discount diamond stud earrings.
Jade mining in Burma has not changed much since the days of its discovery. The best deposits were found in the hills north of the Uru River. At these Tawmaw mines, just as had been done in Turkestan, fires were built on the rock face to crack the jade, which could then be split out by hammer and wedge. Quantities of jade were also recovered as boulders in loose rock deposits along and in the Uru River. Frequently this was better material, and undamaged by the mining fires. Most of the Burmese jade mined was—and is—very pale green or whitish, sometimes with rather sizeable bright green splotches. Much more rarely have the coveted solid-green pieces—in emerald and darker shades—been recovered, and even more infrequently some of lavender color.
