3.1" Green Cubic Fluorite Crystals with Phantoms - China
This is an aggregation of exceptionally beautiful cubic fluorite crystals with light-green coloration. Each crystal contains an internal "phantom" growth zone with deep-green coloration. It comes out of the Hunan Province of China, a region known for its stunning fluorite formations. The crystals are in excellent condition with only some minor chipping to edges, and typical damage along the periphery and underside 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.
