7.3" Blue-Green Fluorite Crystal Cluster - China
This is a gorgeous cubic fluorite crystal cluster that was collected from China. It is quite large and features blue-green colored fluorite crystals that have a somewhat jagged appearance across the top of the specimen and a stepped appearance at the base.
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.
