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!

Scheelite from China - Multi-Color Response under Shortwave, Midwave, and Longwave UV

Description:
There was a recent post in the Fluorescent Mineral Group on Facebook discussing the fluorescence of scheelite under LW UV (UVA). I checked the pieces I have here and found that around half of them are fluorescent a dim orange - not terribly bright (and really requires a powerful LED light such as the Convoy to see a noticeable response). This piece was one of the better ones. (Sadly, as is the case with many rocks from China, no exact locality was given - but my guess is a mine in Hunan.)
