2.2" Glass-Clear, Purple & Green Cubic Fluorite Cluster - China
This is a stunning cluster of glass-clear, green and purple cubic fluorite crystals that formed over a bed of quartz. Many of the purple and green fluorite crystals have bevelled edges. It comes out of the Hunan Province of China, a region known for its stunning fluorite formations. The crystals are in excellent condition with the majority of damage limited to the periphery of the specimen where it was removed from the pocket.
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.
