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!

Calcite, Fluorite, Pyrite - Moscona Mine, Spain

Contributed by: Daniel C. Montero
Date: May 6th, 2026
Locality: Moscona Mine, El Pontón de Solís, Corvera de Asturias, Asturias, Spain (See on Mindat)

Description:
More known for its fluorites of unusual white fluorescence with long phosphorescence in some samples being more common in most a more orange color.

Not only do the fluorites show fluorescence, some calcites also present a beautiful response of a pinkish color, being more common than the non-fluorescence or the orange response by a coating that reminds me of sphalerite in some samples.
