The pics say it pretty well...this is daramatic enough. BUT they cannot convey the stark contrast of the metallic, lustrous sphalerite with the crystallized stark white barite ball, that you see in person. A sphere comprised of ivory colored barite crystals, 7.0 cm across, is perched on a cluster of splendent, brownish-black, sphalerite crystals, to 4.0 cm in length, that exhibit reddish-orange highlights. As a bonus, there are even a few, gemmy golden calcite crystals, to .9 cm across, as accents on both the sphalerite and the barite. Out of allthe rocks here, for the combination of qualities, this to me strikes me as most unique among them. Just love it...
