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 - Puttapa, Australia

Contributed by: FMS Admin
Date: May 4th, 2026
Locality: Beltana Mine, Puttapa, Pastoral Unincorporated Area, South Australia, Australia (See on Mindat)

Description:
A nice small cabinet specimen from the Puttapa zinc mine in Australia. The UV image is 30W SW plus 30W MW. The MW brings out the yellow color which is sometimes found in these rocks. Photographed with a 60mm macro lens at F32 ISO100 8k color temp.
