Here is 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. 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 crystals that matched so well for shape, thickness and size. There hasn't been any significant amount of these specimens on the market in approximately 25 years, and they are often only found in old collections. Ex. Brian Kosnar.
