These crystals have the highest quality you could ever want in a classic Bisbee pseudo. This marvelous pseudomorph has managed to retain the shape of the original crystal in a way that is not at all rough. This complete and “tight” replacement is the standard for one of these bladed crystals and it is fairly large with a striking termination at one end. The Campbell shaft produced the best quality pseudomorphs of malachite after azurite. Ex Paul Zimmerman and Bill McBride collections
