The first thing you notice when lifting this rich specimen of Dyscrasite is its high density, as its weight feels disproportionately large compared to its size.  Prompted by this, I find its density is 9.71 g/cm3, almost ten times heavier than water!  Dyscrasite is a silver antimonide and in this excellent miniature from Wenzel Mine in the Frohnbach Valley of the Black Forest region in Germany, occurs as sub-millimetre, equant metallic grey-black crystals forming granular crystalline masses throughout a creamy to off-white Calcite matrix.  In one area the crystals appear to form a dendritic growth pattern of about 3 cm long, with the micro-crystals aligned sufficiently as to create foliated structures which manifest at the macro-level.  The tiny crystals meld together in parts forming rounded and platy masses.  A rich and excellent example of this rare species from its type locality at Wenzel Mine in state of Baden-Württemberg.
