A superb cluster of six sided, well developed crystals of Pyrargyrite, nicely set on minor matrix. The Pyrargyrite is sharp edged, highly lustrous and excellent terminated. Some crystals are showing an interesting, holey but still very smooth and shiny surface. This is a great small mini from the famous Gang Brahmaputra (Brahmaputra Vein) of Schlema. During the active mining period of the Russians in Schlema, the miners used the names of mainly Indian rivers to designate the veins.
