2.4" Apple-Green Fluorite Crystals with Muscovite - Erongo Mountains

Here is a beautiful cluster of apple-green fluorite crystals encasing schorl, that formed in association with muscovite. It was collected from the Erongo Mountains in Namibia. The cluster measures 2.4 x 1.55" and the largest fluorite is .8" wide.

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.

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.
