10.9" Quartz Encrusted Yellow Cubic Fluorite - Morocco
This is a gorgeous 10.9" specimen of yellow, cubic fluorite that's coated in an aggregation of quartz crystals that nearly cover the entire top of the specimen, from Meknes, Morocco.
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.
