Meta-Autunite

This is an excellent thumbnail specimen of meta-autunite from the renowned uranium-producing Daybreak Mine in Washington. The specimen exhibits the characteristic yellow-green hue, with foliated, platy orthorhombic crystals. It exhibits intense neon green fluorescence under UV light. Mined in the 1950s and 60s, specimens from this active period are now quite rare. The daybreak is a classic U.S. locality for radioactive minerals, and is the type locality for meta-autunite.
