This is a vintage sterling silver seahorse charm pendant. The charm is oxidized to give it a patina and it will not need to be polished as it stays that way. It measures 7/8" tall with the bail ring by 3/8" wide by 1/2" and tested as 925 sterling. This would make a nice addition to a necklace or charm bracelet and it is beautifully detailed.
Thank you for looking!
