Barite    Four La Broque, Puy de Dome, France.  Ex. Dr. Steve Chamberlain Collection.   A rare find this floater crystal is composed of two parallel growth crystals.  It measures 5.5 x 2 x 1.3 cm overall.  Gemmy and aesthetic.  Rough on edges and one termination.  Not perfect but very nice for such a rare thing.  $ 190
