Bismuth (ex Al Kidwell Collection)

Item Description

Please note: This piece was labeled as coming from "Schneckenstein", but I can't find a listing for Bismuth for any locality around Schneckenstein, so if anybody out there has some insight as to where it could be from, please reach out a let us know. The piece is filled with brilliant silvery colored micro crystals and veinlets running through the matrix. The piece is quite heavy for its size, and there is a black mineral (possibly something like Cassiterite or Ferberite?) present that seems to be giving it the weight. From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974 ( https://www.mindat.org/photo-326405.html ).
