2.5" Purple, Cubic Fluorite Crystal Cluster - Berbes, Spain
This is an attractive, 2.5" wide, stepped-cubic fluorite crystal cluster on quartz that was collected from the famous Berbes mining area in Asturias, Spain. The crystals exhibit gorgeous purple coloration and have black inclusions scattered throughout.
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.
