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

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.

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.

Muscovite is a phyllosilicate mineral of aluminium and potassium. It has a highly perfect basal cleavage yielding remarkably thin laminæ which are often highly elastic.
