Item number: 22847

This matrix of coarse sphalerite, galena and pyrite has a cavity exposed on the top of it that is lined with small quartz crystals and then, mostly dolomite crystals and a few sharp pyrite crystals. The dolomite crystals dominate the opening and are creamy-white rhombohedra. Great old locality!! R
