An adjustable ring that takes a 14 mm Rivoli - or any 14 mm stone. Bend the bezel down over the stone to secure. Adjust the ring to the correct size and fold the tabs over the band to hold that size. A fun way to add sparkle to your fingers.
Also works well with the 12mm Swarovski 4470 Cushion Cut. Once you fold down the prongs, you can't tell that the stone is not round.
Lead-free. Nickel-free. By the pack of 2.
