Sapphires — the stone of choice for Napoleon, Princess Diana and Elizabeth Taylor — have been a favorite of aristocrats and the well-to-do since the time of the Ancient Greeks. In 1940, John D. Rockefeller Jr. had Cartier mount a 62-carat sapphire he had bought from an Indian maharajah in a brooch for his first wife, Abby Aldrich Rockefeller; in 2001, the piece sold for a then-record of $3,031,000 at Christie’s New York. The grand dame of jewelry, Elizabeth Taylor had a passion for the gems that her lovers were happy to indulge.Shop a collection of antique and vintage sapphire jewelry from some of the world’s top jewelers on 1stDibs.
