EXCLUSIVE AT NET-A-PORTER.COM. Delfina Delettrez describes her pieces as something you would discover in your grandmother's jewelry box. Made from 9-karat gold, this 'Dot' ring is cast in the label's signature 'Phantom' setting to create the illusion of floating jewels. It's set with a lustrous freshwater pearl and a 0.20-carat pink topaz. Wear yours solo or stacked with the coordinating style.
