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!

Anthophyllite, Clino-suenoite, and Tremolite from the International Talc Company Mine, New York, USA

Size: 6 x 2 x 10 x cm
Weight: 145 g

Description:
Tremolite mixed with “tirodite”, i.e. anthopyllite and/or clino-suenoite. Under long wave UV light the tremolite fluoresces yellow/orange while the antophyllite/clino-suenoite fluoresces red/violet. Under shortwave UV light or 405nm laser the red/violet essentially disappears and the whole specimen fluoresces yellow/orange. As far as I know it is not possible to distinguish the anthopyllite from the clino-suenoite without elemental analysis.
