2.7" Cubic, Blue-Green Fluorite Crystal Cluster - China
Here is a beautiful, 2.7" wide specimen of blue-green fluorite crystals that were collected collected from China. When viewing the fluorite through its crystal face, dark phantoms/zoning can be seen within the crystal. The base of this rock has been cut flat, allowing for aesthetic presentation without the need for a 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.
