Fluorescent 6 Tirodite and Tremolite

Manganocummingtonite (aka Tirodite), anthophyllite, and tremolite are virtually indistinguishable in the field and are all members of the amphibole group of silicate minerals. Regardless, they are beautiful fluorescent specimens and exhibit triboluminescence, as well. Handle with care, as they all are asbestos.

Triboluminescence is a phenomenon in which light is generated when a material is mechanically pulled apart, ripped, scratched, crushed, or rubbed. The phenomenon is not fully understood, but appears to be caused by the separation and reunification of static electrical charges
