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!

Kyanite from the Willis Mountain Mine, Virginia, USA

Description:
Kyanite blades in matrix. Lot\'s of them! In daylight they are essentially colorless, white or light grey, missing their typical blue color. Kyanite often shows a dim to very dim red fluorescence under longwave UV light. In addition to the longware red, this specimen also shows a quite brighter light blue fluorescence under shortwave UV.
