What is Paua Shell?
Found only in the seas around New Zealand, paua Shell is a gem-quality mineral that comes from its eponymous mollusk. The material can seem dull from one side, but on the other side, it shines with marvelous metallic colors. The shells are sometimes polished and sold whole, but they're also used for various souvenirs and decorative objects.
