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!

Hydrozincite, Sphalerite from Green Monster Mine, Nevada

Date: Mar 8th, 2026
Locality: Green Monster Mine, Shenandoah Peak (Shenandoah Mountain), Goodsprings Mining District, Spring Mountains, Clark County, Nevada, USA (See on Mindat)

Description:
One of the many specimens collected in the Green Monster Mine, Sandy Valley, Nevada, in early January 2022. The blue-white fluorescent is hydrozincite (short-wave UV), orange fluorescent is sphalerite (stronger under long-wave UV than short-wave UV).
