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, Tremolite, Talc - Talcville, New York

Locality: International Talc Company Mine (Reynolds Mine), Talcville, Edwards, St. Lawrence County, New York, USA (See on Mindat)
Size: 50 x 10 x 70 mm

Description:
A mixture of anthophyllite (formerly known as manganocummingtonite) and tremolite crystals with minor talc. The anthophyllite fluoresces dim violet in SW and violet, red in LW. The tremolite is orange under both wavelengths, and the talc fluoresces a greenish white in SW.
