A real rarity for this mine, as we think that almost no one has ever noted the presence of Tetrahedrite at Panasqueira. The small brilliant crystals are gray-black and are on prismatic Siderite. There is also some green Fluorapatite, which adds to the interest of the specimen. We will give the buyer a copy of the analysis of the Tetrahedrite.
