Sterling Silver Starfish Post Earrings. These ready to wear earrings, with their sparkly and dainty starfish, are the perfect gift for any beachcomber or ocean lover. Starfish come in all shapes, sizes, and colors, decorating rocks in tide pools, and coral on the ocean floor.

If a starfish is cut in half, two starfish will grow.
