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 and Natrolite - Ilimaussaq Complex, Greenland

Locality: Tugtup Agtakôrfia, Tunulliarfik Fjord, Ilímaussaq complex, Kujalleq, Greenland (See on Mindat)

Description:
When I took this picture, we were not sure what the green fluorescence was. Since decided that it is natrolite.
