Fluorescence: this term is derived from fluorite, which often clearly shows this effect.

The fluorine element also takes its name from fluorite, an important source of the element.

Fluorite is found as a common mineral in hydrothermal veins, especially those with lead and zinc minerals. It is also found in some greisens, granites, pegmatites and high temperature veins, and as a component of some marbles and other metamorphic rocks.

The Fluoriet Group includes:
