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!

Turkey Fat Smithsonite - Rush Historic District, Arkansas

Contributed by: FMS Admin
Date: May 8th, 2026
Locality: Rush, Rush Creek Mining District, Marion County, Arkansas, USA (See on Mindat)
Size: 1.5 x 2 inches

Description:
Simply, one of the best mineral names in fluorescent rocks. Turkey Fat Smithsonite, from the Rush Historic District, Marion County, Arkansas. Very nice fluorescence in longwave, though not much in SW or MW. The material is from an old zinc mining area deep in the Ozarks with several mines having producing specimens. This one is fairly small, at about two inches by an inch and a half.
