2.2" Purple Cube-Dodecahedron Fluorite Cluster - China
This beautiful specimen features lustrous, deep-purple fluorite crystals with unique cube-dodecahedron faces, collected from the Xia Yang Mine in Yongchun County, China.
Fluorite is a halide mineral comprised of calcium and fluorine, CaF2. The word fluorite is from the Latin fluo-, which means "to flow". In 1852 fluorite gave its name to the phenomenon known as fluorescence, or the property of fluorite to glow a different color depending upon the bandwidth of the ultraviolet light it is exposed to. Fluorite occurs commonly in cubic, octahedral and dodecahedral crystals in many different colors. These colors range from colorless and completely transparent to yellow, green, blue, purple, pink or black. Purples and greens tend to be the most common colors seen.
