Incredible and amazing one of a kind ring with drama and fit for a goddess. The materials are oxidized sterling silver, fine silver bezel, 18k, and cobalto calcite druzy. Please note the fine silver bezel can take on a golden glow from the oxidation process. For care, please do not use a polishing cloth as that can alter the patina. You can swish in warm sudsy water, rinse and dry. The surface size is 1 1/2 x 1 1/4. The ring size is 8 1/2
