Cushion Illusion Diamond Ring - R5762Grand in every sense. At the centre of this ring sits a cushion illusion set diamond its soft, rounded square form magnified by a mirror finish setting that makes it appear far larger than its carat weight, delivering the visual presence of a much more substantial stone. Around it, a closed halo of round brilliant diamonds encircles the cushion completely, adding a continuous frame of brilliance that enhances the centres perceived size even further.
