Excellent, colorful specimen of brightly-colored dendritic uraninite with various “gummite” group minerals and green autunite (fluorescent!) with cyrtolite zircon in feldspar matrix from the famous Ruggles mine in central New Hampshire, USA. Measures ~75,000 CPM on my Ludlum Model 3 counter with the 44-9 probe. Rare!!
