Smithsonite (from Washington!)
Miniature, 4.0 x 3.8 x 1.8 cm
Black Rock Mine, Spirit, Stevens County, Washington, USA
Ex. Bob Bartsch
This botryoidal smithsonite, with spheres to 1.7 cm across, is lustrous and slightly translucent with a pleasing tan coloration. Highly unusual locale! This was collected by the late Bob Bartsch, and long in his collection. I have not seen more of these on the market - ever.
