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:
Update: The original post said the 340' Level, Franklin, New Jersey. However, the 340' Level at the Sterling Hill Mine is a well-known location for wollastonite specimens. It is likely that this specimen is from Sterling Hill.
