2.4" Purple & Green Cubic Fluorite Cluster with Quartz - China
These is a cluster of gorgeous light-green and purple cubic fluorite crystal cluster that formed from a bed of quartz. Some of the fluorite crystals have naturally bevelled edges and what appears to be micro-pyrite crystals that give their faces a unique luster. It comes out of the Hunan Province of China, a region known for its stunning fluorite formations.
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, with colorless, pink, and black being the rarest.
