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!

Rich Blue Fluorite Crystals with Phantoms - China

Contributed by: Mark Cole
Date: Apr 9th, 2026
Locality: Chenzhou, Hunan, China (See on Mindat)
