One of a kind ring with loads of sparkle, a great statement ring for any evening. The materials are sterling silver, fine silver bezel, 18k bi-metal, and pyrite in schist. The process is everything is hand sawn, soldered, textured and oxidized. 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 ring is a size 8.
