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!

Contributed by: FMS Admin
Date: May 3rd, 2026
Locality: Puttapa, Pastoral Unincorporated Area, South Australia, Australia (See on Mindat)
Size: 3 inches
