The team at Elizabeth Sarah Collections uses .925 genuine sterling silver. While it is a naturally tarnishing element, it is easily polished back to its natural shine. You can use mild soap and water to clean sterling silver along with a silver polishing cloth. We recommend that you treat it the same way as gold vermeil, keeping it away from moisture, lotions and chemicals. For a deeper clean use Tarn-X and follow the instructions above in the general cleaning and care guide.
