This is Mercurian Tetrahedrite aslo named as "Schwazite", based on locality name. It represents a great rarity for entire Alps and specimens are very hard to obtain. No new finds can be expected from this historic area. The dark grey crystals are up to 11mm across. They show a good contrast to light matrix. Some were contacted or had no room to grow, but there is a group of well shaped, undamaged crystals exposed along on edge, that represents this rare mineral in the best way.
