Inspired by 1960s Swinging London fashion and today's "sphere factor" circular influence in jewelry, this necklace coordinates with the Contempo collection of modern jewelry. Our silver items have a protective lacquer finish to help prevent oxidation. To care for our silver items, simply wipe down your pieces with a dry, 100% cotton cloth. Keep them away from water, jewelry cleaners, silver cleaners, treated polishing cloths, perfumes, hairspray, lotions, hand-sanitizers and make-up. We offer our own that you can safely use.
