A wonderful thumbnail set consisting of a crystal of Aragonite and a pseudomorph of Copper after Aragonite from the famous locality of Corocoro. These "floater" specimens are well known from Bolivia for their great form and color, and this set is great way to illustrate the "before and after" effect which is rare to find for most pseudomorphs, especially from the same locality. It must be noted that single un-pseudomorphed Aragonite crystals from Corocoro are not easy to find, and we spent a good deal of time trying to match the few we have with a pseudomorphed counterpart to create a totally one-of-a-kind pair. These pieces are some of the most well known and highly sought after pseudomorphs around. This set is a very fine example of this material, and it was very difficult to find a pair of specimens that matched so well for shape and size.
