Very large (1.45 cm) meta-autunite crystals in crumbling Granite host rock from the famous Daybreak Mine near Spokane, Washington. The fractured granite allowed these amazing crystals to form and was a veryvhistoric nining locality that is worth reading about. Dark green with fabulous shine like mica. Great neon-green UV reaction. Wonderful rare material in a very nice-sized specimen. Definitely hard to find in such a size.
