Fluorescent Mineral Database

A new secret project! Trying to create a nice Fluorescent Mineral Database (FMDB), which would be searchable by mineral, locality, and luminescence properties. Also making it easy for people to contribute with their own specimens!

Sellaite and Fluorite from the Fontsante Mine, France

Contributed by: FMS Admin
Date: Feb 26th, 2026
Locality: Fontsante Mine, Tanneron, Draguignan, Var, Provence-Alpes-Côte d\'Azur, France (See on Mindat)
Size: 5.5 x 3 x 5.5 cm
Weight: 125 g

Description:
This is an old Sellaite (MgF2) (with minor Fluorite (CaF2) specimen coming from the BRGM (Bureau de Recherches Géologiques et Minières) in Paris (site: www.brgm.fr/fr).
Both minerals are present in "massive form".
The best fluorescence is in LW, but it fluoresces in MW and SW too.
Sellaite is yellow-lemon and fluorite is weak blue gray.
