One of the most interesting and sought after oddities in Chessy are 'eggs' featuring azurite crystals lining shrinkage cracks inside blue nodules! Here is a beautiful representative 'egg' displaying a core with highly lustrous royal blue azurite crystals inside a banded azurite nodule partly pseudomorphosed to malachite at its periphery. A French and international classic!
