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!

Clino-suenoite, Tremolite - Talcville, New York

Contributed by: FMS Admin
Date: May 3rd, 2026
Locality: International Talc Company Mine (Reynolds Mine), Talcville, Edwards, St. Lawrence County, New York, USA (See on Mindat)
Size: 3 inches

Description:
Pink/Red clino-suenonite (LW), orange tremolite (SW, LW). This 3-inch specimen is from the No. 8 Reynolds Mine in Talcville New York. The LW color is quite unique and remarkable. Photographed with a 60mm macro lens at F32 ISO 100.

UPDATE: The original Nature's Rainbows post used the mineral, manganocummingtonite, in the title. The International Mineral Association (IMA) replaced the name manganocummingtonite with the name clino-suenoite for the mineral found at Talcville.
