2.4" Botryoidal Grey-Purple Fluorite - Fremont County, Colorado

This is a unique formation of fluorescent, botryoidal grey-purple fluorite that was collected near Canon City in Fremont County, Colorado. This specimen comes from one of the relatively few known locations where botryoidal fluorite can be found. It has a frosted outer layer which gives it its grey coloration, with layers of translucent purple fluorite beneath. Often these specimens are sold following some time under air abrasion to remove the frosted layer.

The fluorite is slightly translucent and under shortwave UV it exhibits a vibrant green fluorescence. Comes with an acrylic display stand.

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.
