4.15" Yellow Cubic Fluorite Crystal Cluster - Morocco
This is a tightly clustered specimen of yellow cubic fluorite crystals, collected near Alnif, Morocco. Some of these crystals have purple speckle impurities within the cube. The fluorite crystals have excellent blue fluorescent properties under short wave UV lighting.
About Fluorite
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, and colorless, pink, and black are the rarest.
