“A specimen formed by some tetrahedrite crystals of very good size. They show faces of the positive and negative tetrahedron, very sharp and rich in faces. Some of them are coated with a thin golden patina of chalcopyrite, a very aesthetic rarity. They are accompanied by bright calcite that partially cover with a geometrical disposition. A specimen of great aesthetic and interesting by the size of its crystals. Size: 10,0 x 8,3 x 6,0 cm. Main crystal: 4,2 x 4,0 cm.”
