3.6" Purple Edge, Cubic Fluorite On Quartz - Qinglong Mine, China

This is a 3.6" wide cluster of purple cubic fluorite crystals that formed from a quartz encrusted matrix, collected from the Qinglong Mine in the Guizhou Province of China. Under shortwave UV, the fluorite crystals fluoresce a faint purple color.

It 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, with colorless, pink, and black being the rarest.
