8.6" Deep Blue Fluorite on Quartz - China

This is a large, deep blue fluorite specimen collected from the Huanggang Mine in China. The fluorite crystals have a strange rhombohedral/botryoidal structure to them, a typical characteristic of the fluorite coming from this mine. The fluorite crystals encrust the quartz points, beneath.

This specimen 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.
