Inspired by the iconic key ring first introduced in 1969, the Return to Tiffany collection is a classic reinvented. The simple oval design of this necklace makes a bold style statement. Sterling silver, 15.5” chain. Happy to answer any questions! I’ve had this since 2007 but haven’t worn in years. This is an authentic piece — Purchased from the Tiffany store in Bethesda, Maryland.
