3.4" Cubic, Green Fluorite (Dodecahedral Edges) - China

 
 
Here is an stunning, 3.4" wide specimen of green fluorite on a quartz encrusted matrix from the Xianghualing-Xianghuapu Mines in China. The plate is made up of stunning cubic crystals with textured dodecahedral edges of up to .8" in length. The base of this specimen has been cut flat, allowing for aesthetic presentation of the crystals 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.

Silicon Dioxide, also know as SiO2 or Quartz, is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich, hot watery solutions called hydrothermal environments, at temperatures between 100°C and 450°C, and usually under very high pressure. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountains forming, and can be hundreds of millions of years old.
