A good example of the finest grade of Black Coral, designed into the most exquisite original designs, is found at Richard's Gallery located on the harbour in Grand Cayman. All Richard's works are sold with a Certificate of Authenticity and a Lifetime Guarantee. Black Coral carving is neither a traditional Cayman art form nor a long-practiced craft; rather it has been invented and become a unique Cayman industry, all in just over three decades .
