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!

Willemite, Calcite, Aragonite - Puttapa Zinc Mine, Australia

Description:
The yellow fluorescence was a surprise on this piece, but most likely willemite.
