This is a fine specimen of the hemimorphite that ha been coming from Wenshan, China. This is very close to the "electric blue" ones that have been the most popular (though hard to get) of them. It is very lustrous - a smithsonite-like luster - and actually slightly translucent. The color in person is even more intense than the photo shows. This sculptural cabinet specimen has excellent form, especially with the partition heavily coated on both sides with hemimorphite.
