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!

Miller Canyon, Arizona

Date: May 4th, 2026
Locality: Nelly James Mine, Miller Canyon, Miller Peak, Cochise County, Arizona, USA (See on Mindat)

Description:
Consensus is calcite, willemite, hydrozincite, sphalerite, smithsonite, and the yellow is possibly cerussite, but is still under discussion.
