Calcite Crystals with Internal Phantoms, Sweetwater Mine, Reynolds County, Missouri

This spectacular fluorescent specimen, from a classic midwestern location, consists of a large cluster of light tan/yellow colored, waxy textured, scalenohedral calcite crystals on a dolomite matrix with minor chalcopyrite. Each crystal shows a distinct, dark, internal phantom. This piece is from the Sweetwater Mine, Ellington, Viburnum Trend District, Reynolds Co., Missouri. As seen in the photographs, the calcite shows a beautiful bright pink fluorescent response under mid wave UV (302nm). Interestingly, the calcite is only dimly fluorescent red under short and long wave UV (not shown). 15.5 x 9.2 x 6.4 cm, 711 grams.
