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!

Stevensite from Paterson, New Jersey, USA

Description:
Radiating needles of brown stevensite with a little calcite and quartz. The stevensite fluoresces white under any UV wavelength, best longwave, but, under midwave only, it is accentuated by the red fluorescence of the calcite.

Normal light.
