This is a cluster of pale green cubic fluorite crystals, collected in Morocco. The crystals fluoresce bright blue-purple under short wave UV lighting. Portions of the specimen have been tinged a slight orange, likely by hematite inclusions. This specimen has been mounted with mineral tack for museum-quality display.

Calcium fluorite (CaF2) is one of the halide minerals. It forms at shallower depths and cooler conditions than amethyst. Fluorite is a common stone, but most commercial fluorite comes from China, Morocco, and Illinois. Fluorite comes in many crystal forms, including cubes, octahedrons, and more forms.

Conclusions. In this study, the effect of grinding media on the flotation behavior of fluorite using NaOl as a collector was investigated. The results for micro-flotation experiments indicated that the fluorite particles ground by cast iron media showed a lower flotation recovery than those ground by ceramic media.
