Autunite - Autunite - $ 3000 SOLD Daybreak Mine, Spokane, Spokane County, Washington, USA cabinet, 11.5 x 7.9 x 4.3 cm
This is a large and beautiful example of the classic material from Washington, circa the 1950s-1960s. It is an extremely large specimen also, to have survived. Remarkably, it is pristine on that large display face!!! (perhaps there are just a few tiny bruises of no import).IT IS MUCH MORE VIBRANT AND JUST PLAIN BETTER IN PERSON! This is a significant US mineral specimen and , for the size and elegance, a significant example of the species. And I think it is priced cheaply, myself. This comes out of a small midwestern museum collection

This is a large and beautiful example of the classic material from Washington, circa the 1950s-1960s. It is an extremely elegant and large specimen.

BETTER IN PERSON! This is a significant US mineral specimen and , for the size and elegance, a significant example of the species. And I think it is priced cheaply, myself.

MD-20885 - Autunite - - Archived Daybreak Mine (Dahl lease), Mount Kit Carson, Spokane Co., Washington, USA small cabinet, 6.5 x 5.5 x 4 cm
A rich specimen of solid autunite, colored a bright green-yellow. The crystals are of the form of thick wheatsheaves representative of the best specimens from this classic mine, and not found in this quality for decades. This piece, in fact, is a proven oldtimer as it has a label from New York dealer Hugh Ford that is probably from around the mid-1900's. Note the value put on it by this respected old dealer, which was a lot of money for the time and surely a sign of his opinion that it is a remarkable large specimen! Commensurate with its age, it has a bit of damage in the form of minute yellow spots on the otherwise yellow-green crystals (plus some contact at the base), and while this affects the price (which otherwise would be $2000-plus), it does not detract visually very much. The piece can be stood vertically as I prefer (top row) with wheatsheaves sticking up, or horizontally as shown in the bottom row. 6.5 x 5.5 x 4 cm
