Mineralogically fascinating specimen with multiple generations of paragenesis. The specimen is, at the core, a sulfide of Pyrite and Chalcopyrite. Outward from this mass grew large 1cm Quartz crystals upon which a layer of Ankerite was deposited. Finally, sprinkled upon the Ankerite are tiny, but very flashy, slender Wolframite crystals. Excellent specimen!
