Sphalerite,Calcite, Fluorite and Rhodochrosite on Quartz

A wonderful combination piece with a bed of jackstraw quartz on which we find clusters of sphalerites, some pale lilac cubic fluorites, a few yellowish calcites and rhodochrosite both as a coating and as rhombohedral crystals. From the Sam Koster collection.
