Description
Fluorite (Alien Eye)
Erongo Mountain, Usakos and Omaruru Districts, Erongo Region, Namibia
3½ by 2¾ by 2 inches (8.9 x 6.9 x 5 cm). Custom LED lighted lucite base.
A fluorite specimen that is black on the outside with a clearly defined, emerald green center that seems to have an otherworldly glow evoking an “Alien Eye” effect.
The “Alien Eye” effect demonstrated here comes from the contrast between the main body of the green fluorite and the black phantoms that provide an otherworldly glow.
Also known as fluorspar, fluorite is often transparent, making it valuable in the production of various types of glass. The mineral form of calcium fluoride, fluorite takes on various hues due to impurities, with the emerald green specimen offered here as a prime example.
