More information regarding fluorite:

Fluorite is the mineral form of calcium fluoride, CaF₂. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.

One of fluorite's more unusual properties is that it will fluoresce, or glow, under ultraviolet light. It was one of the first materials in which the phenomena of fluorescence was recognized and studied, and the term 'fluorescence' actually comes from the mineral name 'fluorite'
