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!

A large cabinet sized calcite from Belgium

Locality: Bertrix, Luxembourg, Wallonia, Belgium (See on Mindat)

Description:
Quite a bolder and a quite pretty bicolored one! Locatlity: Bertrix, Luxemburg, Belgium. I haven\'t a clue what causes the somewhat \"special\" fluorescence. Clearly different generations of calcite in an apparently fractured configuration... Seen under SW and MW-UV.

Fluorescence under shortwave and midwave UV light.

Summary of luminescence responses:

  • Fluorescence under Midwave (305nm Lamp/Mercury) UV light: White
  • Fluorescence under Midwave (305nm Lamp/Mercury) UV light: Red
