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!

Zunyite - Big Bertha Mine, Arizona

Contributed by: FMS Admin
Date: Feb 21st, 2026
Locality: Big Bertha Mine, Middle Camp-Oro Fino Mining District, Dome Rock Mountains, La Paz County, Arizona, USA (See on Mindat)
Size: 3.8 x 1.6 x 6.4 cm

Description:
Tiny (1mm) colorless to brown zunyite crystals in quartz matrix, fluorescing deep red in SW. Yellow-fluorescing microcrystals of what is likely pyrophyllite appear as grains around and on the zunyite. A macro closeup is included with FOV 20mm.
