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!

Smithsonite, Cerussite and Hydrozincinte from the Zorzone Mine, Lombardy, Italy

Description:
Pocket of smithsonite crystals on matrix. On top of the smithsonite there are a few small cerussite crystals. Under longwave UV light both the smithsonite and cerussite fluoresce yellow. Under shortwave UV light, the smithsonite is not fluorescent anymore, but the cerussite keeps a light yellow fluorescence. Most notable under shortwave UV light is a bright blue fluorescence mineral, likely hydrozincite. Under shortwave UV light there is also an unidentified red fluorescent mineral.
