Antique Gold, Agate, and Diamond Star Locket

Located on Madison Avenue, Fred Leighton has been a haven for serious vintage jewelry collectors since the 1970s—a trusted authority on everything from Georgian and Victorian to Art Deco and contemporary pieces. Diamonds from Cartier and Tiffany sparkle alongside originals by Suzanne Belperron, JAR, and David Webb; Mr. Leighton himself is credited with elevating vintage jewelry from overlooked to deeply desirable. The shop has dressed everyone from Jackie Onassis and Elizabeth Taylor to red-carpet regulars like Gwyneth herself—proof that pieces spanning the 1700s to the 1970s can feel surprisingly modern.
