Fantastic intergrown Galena cubes with iridescent Chalcopyrite on Dolomite matrix from Sweetwater Mine, Ellington, Reynolds Co., Missouri, USA. Another fantastic specimen from the celebrated Sweetwater Mine, featuring sharply defined three intergrown galena cubes perched on a pale dolomite matrix accompanied by iridescent Chalcopyrite crystals. This is an old specimen from the 70's. Adding to the visual drama, flashes of iridescent chalcopyrite are scattered across the Dolomite crystals on one side, displaying lively rainbow colours that glow against the galena and dolomite backdrop. Sweetwater Mine is renowned for producing world-class mineral combinations, and this specimen perfectly showcases the locality’s signature associations. With the geometric beauty of galena, the glowing allure of fluorescent calcite, and the shimmering iridescence of chalcopyrite, this is a top-tier collector’s piece embodying the mineralogical richness and aesthetic appeal for which Missouri is famous.​
