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!

Calcite, Fluorite and Willemite from Hidalgo County, New Mexico

Description:
This beautiful 3-color fluorescent rock features a combination of calcite, willemite and fluorite and is part of a find made by New Mexico based collectors Ken and Gail Hennig, who found several pieces of this material while on a collecting trip in the area of Hidalgo County, New Mexico. Ken and Gail named this find "Enchantment Rock" after the state of New Mexico- the Land of Enchantment.
