Here we have a beautiful Black Forest specimen of well developed Pyrolusite from the well known Gremmelsbach locality near Triberg. Actually this stuff occurs just as this one in spherical sprays,- but here we have additionally plenty WELL TERMINATED crystals. This circumstance is super rare for the locality. The Pyrolusite here is also in fresh condition with fine metallic sheen. This kind of material comes definitely from the great finds at the end of the 1970s and is not comparable with the recent finds.
