From the classic mining district around P?'bram in Bohemia, Czech Republic, a single upright standing curved blade of silver Bournonite (lead-copper antimoniate) with a bright metallic lustre. The crystal measures 1.5 x 0.8 x 0.4 cm and sits in a bed of equant, stubby colourless Quartz crystals. Partly attached to the Bournonite is a cluster of micro, slightly curved rhombohedral white crystals, most probably Dolomite. One section of the Bournonite crystal could have a chip missing, based on what appears may be a fractured surface, but this could be a natural parting of the gaps within the 'cog-wheel' habit of the crystal, it is difficult to tell.
