Pyrolusite ps. after Calcite

ID: CC19165
An excellent pseudomorph of coal-black metallic Pyrolusite replacing a stack of rhombohedral Calcite crystals to 1.8 cm long.  This miniature is from Ilfeld in the Harz Mountains and is associated with minor Chalcopyrite on the back face.  Small spherical structures of sooty-black Pyrolusite are occasionally dotted over the pseudomorphed crystals.  A fascinating specimen from Ilfeld.
