A colorful mineral both in visible light and ultraviolet, Fluorite is composed of Calcium and Fluorine and has a wide range of uses from ceramics, metallurgy, optics, and lapidary. When found in nature, many fluorites form isometric shapes, including cubes and octahedrons. Color zoning within these crystals are common, and enhances the beauty of the crystals.
Grape-like crystals have formed in rare curved octahedral structures, surmounting a sea-green backdrop of Fluorite. This is one of the premier Fluorite specimens of this type from the famous find in De'an Fluorite Mine, Wushan, De'an Co., Jiujiang Prefecture, Jiangxi Province, China.
