Wenshan, Yunnan Prov., China
Miniature, 5.2 x 3.7 x 1.6 cm
Spheres, to 6 mm across, of lustrous and slightly translucent, rich, sky blue gibbsite, an uncommon aluminum hydroxide, almost totally cover a sliver of matrix. This new find is possibly the world's best of species for intensity in coloration. Very pretty material! Very lightweight. One of the better quality pieces I saw for sale in a whole table of the material laid out at the Shanghai show in April 2012.
