2.3" Purple Cubic Fluorite Cluster - Namibia
This is a richly-colored, 2.3" wide cluster of cubic fluorite crystals, collected from Karas, Namibia. The crystals are deep-purple and contrast nicely with the iron oxidation on the quartz matrix. This region is known for its botryoidal fluorite specimens of the same color.
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.
