3.75" Very Clean Purple Cubic Fluorite on Quartz - China
This is a very aesthetic group of very well defined, dark purple, cubic fluorite crystals on a bed of quartz. It's a new find from Qinglong, Daoping Provice in China.
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.
