Here is a wonderful thumbnail size specimen of the famous pseudomorphs of Copper after Aragonite from Corocoro. These well-known floater specimens from Bolivia are desired for their sharpness and color, and this fine example has the classic and unique form that has made these pieces some of the most sought after pseudomorphs around. This is a particularly sharp example from older finds. ex Richard Kosnar collection (he specialized in Bolivian minerals from the 1970s on).
