Our Florida jeweler, Charles, handcrafts each red abalone statement ring with his signature nickel-free, lead-free, hypoallergenic, gleaming metal alloy. Harvested from the shells of sea snails, this gorgeous, richly-colored abalone is breathtaking and unique. Handcrafted for Uno Alla Volta, from the heart and hands of the artisan. Dimensions- 1 inch long, adjustable. To care for this ring, use warm soapy water and a dry cloth to clean it. Do not use liquid jewelry cleaners or polishing cloths, as this may compromise the lacquer.
