Stromeyerite is an uncommon silver, copper sulfide and this rich and showy silver ore specimen hails from the Type Locality in Pribram. Burnished native silver clusters, in crystals, wires and massive form are aesthetically perched on a sculptural matrix of thick veins of moderately lustrous, dark gray, massive stromeyerite in massive to crystallized quartz. Probably an older specimen, but no proof for sure as Josef may have collected it himself as well. Ex. Josef Vajdak Collection, a Pribram specialist.
