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!

Fluorite and Cerussite from the Blanchard Mine, New Mexico, USA

Description:
White fluorite cubes covered by secondary lead minerals, mostly (?) cerussite. The cerussite is powdery white, but it covers a translucent mineral which is not (or weakly so) fluorescent. Biggest fluorite cubes are between 8 and 10 mm in size. In the matrix there are some shiny galena cubes, only partially visible.
