7.8" Glassy Green Cubic Fluorite and Calcite on Quartz - China
This is an aggregation of phenomenally clear, pale green cubic fluorite crystals over lustrous milky quartz. The reverse side of the specimen contains a massive, 2.75" rhombohedral calcite crystal! It comes out of the Hunan Province of China, a region known for its stunning fluorite formations. The fluorite fluoresces purple under short-wave UV light, and the calcite fluoresces a bright pink. It even shows some scant phosphorescence!
About Fluorite
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, and colorless, pink, and black are the rarest.
