1.9" Botryoidal Green Fluorite Crystal Cluster - China
This is a beautiful specimen of botryoidal green fluorite from the Henan Province of China. The fluorite formed in layers and displays magnificent purple fluorescence under long wave UV. Various layers of fluorescence can be viewed when shining the UV lighting along the edges of the specimen.
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.
