2.1" Green Fluorite Crystal Cluster - South Africa

This is a beautiful cluster of green octahedral fluorite crystals that were collected from Riemvasmaak in South Africa. Under both short and long wave UV, these crystals exhibit a vibrant purple color.

Riemvasmaak is a small town that's located in the Kakamas District of South Africa. It's well renown for the octahedral fluorite crystals that are produced from the Kakamas Zone of this region. This zone is located around the Orange River in South Africa, where countless quartz and fluorite veins can be found. The fluorite from this zone is primarily a vibrant green color, with the highest quality specimens featuring wonderful transparency, though other colors (orange, purple, blue, colorless and yellow) of fluorite aren't unheard of.

The fluorite is often found with an aggregation of quartz that coats the crystals. Various methods are used to remove this quartz, however in some cases the quartz crystals will be left on this specimen, though this typically depends on the quality of the crystals.

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.
