Fluorite: The Overachiever of the Halide Mineral Family

by Laura Konst
Fluorite named fluorescence, defined hardness 4 on the Mohs scale, and its low-dispersion optics end up in high-end telescope and camera lenses. For a mineral with just two elements in a cubic structure, it has accumulated an improbable scientific CV. This guide covers the colour science behind its extraordinary spectrum, the octahedral cleavage geometry, the fluorescence history, and what Rainbow Fluorite banding actually records.
