Description

Crystals of arsenopyrite to 1 cm protruding from a sulfide matrix.  There is secondary acanthite mixed in with the arsenopyrite but despite the old label i am not convinced any argentite. Galena, sphalerite, pyrite, and chalcopyrite are in matrix along with possible sulfosalts.  I received the piece in an exchange several years with an engineer at Wismut who told me Eham is a shaft in the Erzebirge area but other than this label i have no other information it is however an aesthetic piece of sulfide ore
