Description: Red realgar needles (up to 1 cm) in vugs of grey dolomite rock from Mücke open pit, Ronneburg uranium district near Gera, Thuringia. The small village Culmitzsch fell victim to the open pit in the 1950s and in memory to the local tavern the quarry was called "Mücke" (mosquito). There are hardly any minerals known from Culmitzsch - but some of the best German realgar samples.
