A superb, metallic grey-black Tetrahedrite crystal measuring to 2.1 cm with part-formed Tetrahedrite crystals around it, on a white Dolomite-Quartz matrix. From Schwaz in the Brixlegg-Schwaz Area of the Tyrol, Austria, the upper half of the crystal forms a four sided regular pyramid with a truncated apex and bevelled modifications to its corners and edges. The Tetrahedrite crystals sit on a splintery block of opaque milky Quartz with occasional spots of green Malachite.
