Made of .925 Sterling Silver. We use a non tarnish silver, a hand made tapered bale, and an oxidized finish to bring out the detail. The Diving Fin Charm will bring back the amazing coral you touched 30 feet below the surface while snorkeling in the Bahamas. Like all our charms, the Diving Fin is USA made. Wear it as a pendant on a necklace or as a charm on a bracelet. We have a simple rubber bracelet or cord necklace if you plan to wear it swimming.
