ID: CC19980
This excellent and rare specimen of crystallised Acanthite with Nickeline is from Měděnec in the Ústí nad Labem Region of the Czech Republic; a copper mining district that worked a copper skarn deposit.  Skarn, a Scandinavian name for “rubbish”, describes where an igneous intrusion has contacted a carbonate horizon, hence causing metamorphism adjacent to the contact.  The Acanthite, a low temperature silver sulphide, forms intergrown, silvery lead-grey crystals which form a 1 cm thick and 4 cm long cylindrical band, folded around two sides of the specimen.  Individual Acanthite crystals are also dotted over the inner core of micro-Quartz encrusted chocolate-bronze Nickeline, a nickel arsenide.  An interesting mix of these silver and nickel species from Měděnec.
