Claudia's signature, and iconic design, The World is Your Oyster, has become a bestseller for its easy-to-wear design and touching sentiment. The disc is cast from an oyster shell found on a beach near Claudia's birthplace in Australia. Much loved by Claudia Bradby collectors, this special necklace can be worn on its own or layered. The adjustable length allows this necklace to be worn as a choker as well as at a more regular length.
