A splendid 3.5 cm diameter, flying saucer-like flattened rhombohedral crystal of Calcite completely included with finely disseminated Boulangerite which makes the entire specimen coal-black. The highly distorted rhombohedron displays perfect threefold symmetry on both sides with a “Mercedes” emblem-style pattern. From Herja mine at Chiuzbaia, Baia Mare in Romania, with a much smaller 1 cm diameter similar crystal attached to one side. A great example of Boulangerite included Calcite crystals from Herja mine.
