4" Botryoidal Green Fluorite Crystal Cluster - China
This is a beautiful specimen of botryoidal green fluorite from Henan Province, China. The most superficial layer of fluorite formed from a layered formation of quartz and fluorite crystallizations. The base of this cluster has been cut flat, allowing for aesthetic presentation without the need for a 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.
