Brand New. Absolute gorgeous Phantom Fluorite with rainbow striations, UV reactive, with calcite. Occurring in all colors of the rainbow and used for a variety of manufacturing purposes, fluorite is recognized as the state mineral of Illinois. Fluorite crystals formed 150–200 million years ago when hot water containing fluorine and other minerals was forced up through cracks in the earth where it interacted with the calcium-rich limestone bedrock. Crystals formed along cracks and in other open spaces in the rock. Fluorite (fluorspar) mining got its start in Illinois in 1842. The mineral is usually referred to as fluorite, while the product that is mined is called fluorspar. It was used as a flux to help remove impurities while smelting metals like iron and aluminum. It also is used in products ranging from optical lenses to fluoride (derived from fluorite) in toothpaste.
