Autunite (Ref: 17.1-551)
Daybreak Mine, Spokane County, Washington, United States
55mm x 42mm x 22mm
minID: 4M7-FYQ
A fully crystallized plate of Autunite from the old sixties vintage finds at the Daybreak Mine. Now considered American classics, this piece has been stabilized to keep it from crumbling as many did. As the Autunite looses water in dry air they tended to alter to Meta Autunite and fall apart. Vivid fluorescence as was typical for these, this specimen came from the Les Hitchings collection, obtained in 1970. Good color and form in excellent condition. From: Well-Arranged Molecules
