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!

Description:
From the lithium pegmatites in the Padrón river, Estepona, Malaga, Andalusia, Spain, better known for their beautiful elbaite and rubellite crystals found by the Mancilla brothers in 1988, we can also find lepidolite crystal clusters with yellow fluorescence under shortwave UV light and blue microcline.
