Uraninite

Ex. Greg Boles Collection

Absolutely outstanding razor-sharp 2 cm. Uraninite crystal from the famous Swamp Quarry in Maine. For this classic locality, this is the best thumbnail-size crystal I probably have personally ever seen. Very well-formed, large, and complete. These were collected by Cliff Trebilcock in the 1960’s and 70’s and are almost unheard of in this quality today. Measures ~80,000 CPM on my Ludlum Model 3 Counter with the 44-9 probe. Rare!
