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:
Certainly not the most impressive fluorescent mineral, but it is quite rare any many people don\'t even know that it can fluoresce. It isn\'t the greatest photo (due to the long exposure) but it is probably the only one out there... The weakest red.
