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:
Fluorite variety: chlorophane from McHone Mine pegmatite, Mitchell County, North Carolina, USA in a Brilliant Emerald cut by Robert Drummond from rough acquired from Loretta Warlick. Faceted February 2, 2015.

It fluoresces very dimly green and is thermoluminescent as many fluorites are. However it being non-reversable I only tried the thermolumonescence on som cuts from the rough also supplied by the faceter.

Summary of luminescence responses:

Fluorite

  • Fluorescence under 405nm blue laser: Blue
  • Fluorescence under Daylight: White
