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!

Baryte from the Meikle Mine, Nevada, USA

Description:
Baryte crystals on matrix. Very sparkly in daylight and bright white fluorescence under longwave UV light. A lot of the crystals are broken or internally fractured, but they also show some interesting fluorescence zoning.
