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)
Size: 1.25 inches

Description:
Beautiful "stained glass" from Puttapa Australia. Before you get too excited about this piece, know that it is about the size of a US half dollar. A thumbnail. However, it exhibits a wonderful "stained glass" look. There are two UV images. The first one is LW+SW, and second SW. Both UV pictures were developed with helicon focus. 12 photo stack at F7.
