One of a kind fun earrings with black onyx and blue opal petrified wood. Very easy to wear, right for any occasion. They are set in sterling silver, with fine silver bezels, oxidized with a French hook. The size of the earrings are 2 1/8 x 3/4. Please note the fine silver bezels 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.
