2.2" Apple-Green Fluorite Crystals over Schorl - Namibia

Here is an association of green fluorite and black tourmaline (schorl), collected from the Erongo Mountains in Namibia. The fluorite crystal formed over black tourmaline (schorl) crystals and muscovite. The fluorite exhibits some slight purple fluorescense under short wave UV.

The specimen has been mounted to an acrylic display base with mineral tack.

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.
