Native Silver pseudomorphing after Dyscrasite

The ancient mining district of Příbram in the Czech Republic produced many fabulous pseudomorphs of Native Silver after Dyscrasite.  These make spectacular specimens because the Dyscrasite, a silver antimonide, forms large well-developed crystals which become spectacular pseudomorphs.  In this gorgeous small cabinet specimen, the former Dyscrasite crystals have grown to 4 cm long and form flattened slender, deeply furrowed tabular crystals, themselves now replaced with Native Silver.  This fabulous small cabinet specimen is heavy to lift and has a completely metallic feel.  The crystals have a sooty dark grey surface coating with a matt lustre and on inspection, the large visible areas of dull silvery white Native Silver are seen to perfectly replace the Dyscrasite by exhibiting ever finer detail of the original crystallography.  A superb specimen from the famous Příbram Mining District.
