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!

Sodalite on Feldspar - Sagasen Quarry, Norway

Contributed by: Mark Cole
Date: Mar 31st, 2026
Locality: Sagåsen Quarry, Sagåsen, Auenlandet, Porsgrunn, Telemark, Norway (See on Mindat)

Description:
The feldspar on these pieces is quite fluorescent. The sodalite is dim shortwave UV but bright longwave UV - best displayed under both wavelengths.
