Description: Mass: 1250 g MIM number:2151 Group of very sharp and separated gray bismuth crystals, with small scattered white dolomite rhombohedra offering a beautiful contrast. Some faces of the bismuth crystals have a hopper formation. The base is coated with micro-crystallized erythrite of purple-red color, which is characteristic of this mine. This sample was found as is and was not acid-etched to free it from its gangue as shown by the perfect state of the dolomites. Photographer: Malte Sickinger Ex collection: Georg Gebhard (Germany)
