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 - Elmwood Mine, Elmwood, Tennessee

Contributed by: Mark Cole
Date: Mar 29th, 2026
Locality: Elmwood Mine, Carthage, Smith County, Tennessee, USA (See on Mindat)

Description:
I gave a UV light to a miner when the Elmwood mine was active. He brought it into the mine and started exploring. This was really all he found of significance before the foreman caught him with the light. One and only chance to lamp Elmwood and it got cut short.
