Despite just a thumbnail specimen, but this is a really good one with great aesthetics. It features several well formed and multifaced crystals of Chloanthite from the old time Saxonian locality Schneeberg. They are sharp edged, highly lustrous and almost superb terminated. Chloanthite was discredited as a species; originally considered (Ni,Co,Fe)As2-2.5, generally now applied to a supposed arsenic-deficient variety of, or synonym of, Nickelskutterudite, ideally NiAs3, though at least some is a mixture, and any As-deficiency is probably not significant. Renamed nickelskutterudite in 1892 by Elwyn Waller and Alfred Joseph Moses. In any case a super thumber with great aesthetics.
