Large natural gold nugget found in Arizona, 156.43 grams, 95% fine. 156.43 grams. roughly 1-5/8" x 7/8" x 7/8". Knobby but smooth, with large rough pits harboring reddish toning here and there punctuating an otherwise glossy bright exterior, somewhat boxy in shape and impressively weighty for its compact size, an attractive relic that spent eons rolling around riverbeds before being plucked by a lucky prospector.
