Item number: 14127

Sharp, complex crystals of pyrite are piled up over a single, dark brown crystal of sphalerite. The pyrites are really overgrowths of pyrite on pseudomorphs of pyrite after marcasite but the pseudo's are so thickly encrusted with the overgrowth crystals, it is hard to tell. Sphalerite was the ore mineral at the Nanisivik Mine. Looks good.
