Larger View
These unusual specimens are formed when liquid bismuth is allowed to cool and crystallize inside a chicken egg. The eggshell is then removed and the surface of the bismuth is brushed bright. Inside an amazing array of crystals form looking like stairs in a painting by Escher. Intricate, beautiful, and amazing. No two are alike. Stand is included. Quite rare.
