IRENE NEUWIRTH One of a Kind 18-karat rose gold, opal and diamond necklace

Cast from 18-karat rose gold (750), Irene Neuwirth’s 'One of a Kind' necklace showcases a luminous opal cabochon. The centerpiece is encircled by a delicate halo of full-cut diamonds, suspended along a classic oval-link chain that offers a subtle contrast between the prismatic stone and the delicate diamond surround.
