Physical properties

Formation & geological history

Formed in hydrothermal veins and sedimentary deposits. While natural fluorite occurs globally, specimen-grade shapes like this are often factory-cut and sometimes dyed or heat-treated to enhance the deep green hue seen here.

Uses & applications

Used in the manufacture of hydrofluoric acid, as a flux in steel making (industrial), and widely used in decorative jewelry, lapidary arts, and 'crystal healing' collections.

Geological facts

Fluorite is well known for its fluorescence under UV light. It is often called 'the most colorful mineral in the world' because it originates in almost every color of the spectrum. The term 'fluorescence' is actually derived from the mineral name fluorite.

Field identification & locations

Identify in the field by its cubic or octahedral crystal habits and its inability to scratch glass (glass is harder). Commonly found in China, Mexico, South Africa, and the USA (Illinois). Collectors should look for internal fractures or 'veils' to distinguish natural pieces from colored glass imitations.
