A mussel seashell, found on one of the beaches on Cape Cod, was molded and cast in sterling silver to create this keychain.  The shell is approximately 3/4 inches (2.1 cm) wide by 1 3/8 inches (3.4 cm) tall, and oxidized to accentuate the details.  The split key ring is nickel plated. Also available as a sterling silver bracelet and pendant.
