BBT94AO8: Druse with very sharp Cuprite crystals with the dominant octahedron and with smaller forms of the rhombododecahedron and the cube, translucent, with great luster and a bright red color. On matrix and with white fibrous aggregates of Dickite. With better color and luster than usual, it is of great quality for the locality.
It comes from an important European collection.
