In this, the ultimate tide pool-inspired beach ring, I've bezel set a sweet little black beach stone with white inclusions and mounted it on an adjustable wrap ring made from cast sea urchin shell. The intricate detail from the sea urchin shell really pops with the oxidized finish and the little bumps on the inside of the band make it feel good on your finger. Because the stone setting is only attached on one side of this wrap ring, you can adjust the size to fit just about any finger. Let me know in a comment what size you would like it - and it will show up sized for you - but you can also tighten/loosen as you wish.
