IRENE NEUWIRTH 18-karat rose and white gold, opal and diamond necklace

The opal on Irene Neuwirth's necklace has a bright, dreamy iridescence, and catches the light beautifully. The stone is one-of-a-kind, and set in 18-karat rose gold that complements its warm, peach tones. It has an 18-karat white gold ring shimmering with diamonds.
