Fluorite

Fluorite (also called fluorspar) is the mineral form of calcium fluoride. It is one of the most varied coloured minerals in the mineral kingdom, and the colours may be very intense and almost electric both in visible and ultraviolet light. Mineral collectors prize fluorite for its very wide range of colours, but it’s best known for purple.

Treatments: Fluorite is typically un-enhanced. However, some materials may have been enhanced through irradiation gamma rays to create interesting neon colours.

Care: To clean fluorite, use warm water and a mild soap. Wash the surface of a soft cloth and remove any soap residue. Do not use harsh chemicals or abrasives because they present a high risk of damaging the surface of the fluorite. Since fluorite is a coloured mineral, the use of ultrasonic cleaners or steamers is not recommended.

Fluorite is well known and prized for its glassy lustre and rich variety of colours, it fills cracks and holes in sandstone, and it is found in large deposits in limestone.
