Description

The specimen is developed as floater. A large azurite crystal was replaced by malachite. The specimen is completely hollow, only the silhouette is still present and covered by malachite. In one further step of genesis sparkling, snowy white cerussite crystals grew inside the replaced azurite crystal and also around it. Really an exceptional pseudomorph sample and in perfect condition all around.
