3.7" Colorful Fluorite Crystal Cluster - China
This is a gorgeous, 3.7" wide cluster of cubic fluorite crystals that were collected from China. The fluorite crystals exhibit a wonderful mixture of blue, green and teal coloration with some zoning within most of the crystals.
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.
