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!

Description:
This is a large specimen of interesting sodalite and ussingite from Tunulliarfik, Greenland. It exhibits an unusual pastel fluorescence. The first picture is all wave UV plus some white light. Some areas of the sodalite are mildly tenebrescent. All photos taken with a 35mm lens at F22, ISO 100, AWB.
