I've had these earring findings for so long, they are nearly "vintage". I've never used them, so they are in excellent condition. They have a wonderful, delicate, finely detailed shell texture, with a matte gold finish. They are heavy-ish - maybe brass underneath. They are a good size - about 18mm side to side, and 18mm from the ring to the other edge. They have a post and clutch that (I think) are surgical steel. Perfect for your sea-themed dangle!
