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!

Taseq Tugtupite on Analcime - Taseq Slope, Ilimaussaq Complex, Greenland

Locality: Taseq Slope, Ilímaussaq complex, Kujalleq, Greenland (See on Mindat)

Description:
This material was the first major discovery of fluorescent tugtupite outside of the famous Kvanefjeld tugtupite mines. Prior to 2001 only gem tugtupite from the mines was well known.
