Barite on Calcite   Elk Creek, Meade Co., South Dakota.  Ex. Nancy Collins Collection.  Certainly a classic American specimen that is uncommon to find on today’s market.  This one has a pair of parallel growth crystals which are transparent and a rich brown color.   The barites are up to 4.3 cm each rising off well formed, yellow calcites.  One crystal has a tip ding on its backside.  The specimen displays best with support so I have it attached to an acrylic plate at this time.  It is 7.5 x 5 x 2 cm in overall size and there is an exceptional luster to the barites.  950$ half price... $475
