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 from Eminence, Missouri

Contributed by: FMS Admin
Date: Mar 8th, 2026
Locality: Eminence Quarry, Eminence, Shannon County, Missouri, USA (See on Mindat)
Size: 16 x 24 cm

Description:
Self-collected by private invitation to a local calcite mine on June 12, 2016. It was a dangerous environment. We collapsed a section of the wall about 12 feet wide by 25 feet tall, probably 50 tons. All was safe and the finds were amazing... this one is sort of red, white, and blue.
