8.6" Epic, Deep Purple Fluorite Cluster with Muscovite - Mongolia

Epic, Deep Purple Fluorite Cluster with Muscovite - Mongolia #173035

This is a stunning association of purple fluorite crystals and muscovite aggregations, collected from Inner Mongolia, China. Many of the fluorite crystals have transparent windows that allow for the interesting zoning within the crystals to be viewed. When a light source is held against the fluorite, vibrant purple and blue colors can be seen within. Under shortwave UV, these fluorite crystals fluoresce purple through their transparent faces.

Comes with a display stand.

About Fluorite

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, and colorless, pink, and black are the rarest.

Muscovite is a phyllosilicate mineral of aluminium and potassium. It has a highly perfect basal cleavage, yielding remarkably thin laminæ that are often highly elastic. It can be colorless or tinted through grays, violet, or red, and can be transparent or translucent. Fuchsite and mariposite are green varieties of muscovite, owing their green color to chromium impurities. Alurgite is a manganese-bearing, purple to reddish variety of muscovite.
