Smithsonite (Ex. J. Schneider Coll.)
Very sharp rhombs of lustrous smithsonite intermixed with dark sulfides (probably tennantite and galena) and micro quartz crystals. The color of the crystals are a pale pink with yellow/tan zones, which is difficult to capture on camera. The crystals are in perfect condition and the unusually zoned coloration is much better appreciated in person. I would be tempted to call it cobaltoan, were it not for the yellowish zones.
