Item number: 22914

A couple of larger, very curved, "saddle-shaped" composite calcite crystals sit on a matrix of smaller calcite crystals, which are, in turn on massive sphalerite, the ore mineral at the mine. The large calcite crystals are tinted grey due to inclusions of fine, hair-like boulangerite crystals. Displays very well!
