5.6" Purple Fluorite Crystals on Druzy Quartz - China

This specimen contains beautiful purple-green fluorite crystal aggregations, sitting atop a bed of druzy quartz. The crystals contain green phantoms within the primarily purple fluorite. There is some minor damage to some of the edges of these fluorite crystals. Under long wave UV lighting, these fluorite crystals fluoresce a vibrant purple.

This crystal association was collected from China, however the specific locality within China is unknown.

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, with colorless, pink, and black being the rarest.

Silicon Dioxide, also known 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.
