Fluorite Chocolate Brown Cubes Celestite Ice Blue Crystal Cluster Rocks and Minerals Mineral Specimen UV Fluorescent Clay Center Ohio

This is a stunning specimen from a well-known American locality! This cluster is rich brown Fluorite with lustrous faces, punctuated by delicate sharp blades of Celestite (or Celestine), a beautiful ice blue mineral which crystallizes in the orthorhombic system. It features unique and striking growth patterns—the dark brown fluorite cubes are well-formed, the flat tabular crystals are gemmy and ice blue (though many are broken or incomplete.) Fluorite and Celestite both may occur in a number of different color combinations, but this color combination is a signature of Clay Center, Ohio. The geode shape and combination of minerals are particularly distinctive. It is a cluster that is striking and beautiful, in both visible and ultraviolet light: Clay Center is known for its highly reactive ultraviolet reactions, and this is no exception. The cluster fluoresces a soft butter yellow with darker zones in the iridescent areas. This would make a wonderful display piece for any collection! C
