Created by Cartier Paris circa 1997, this beautiful boule ring is set with a 10-carat plus Ceylon sapphire mounted in platinum and 18K gold. The high domed ring centers a Ceylon sapphire weighing 10.98 carats, flanked by pairs of carved sapphire leaves, and surrounded by sapphire and emerald beads. A dome ring in the taste of Jeanne Toussaint, with elements of the firm's 1920s "Hindou" or "tutti frutti" style, this glamorous jewel set with a specimen sapphire reflects Cartier's history of leadership in avant garde design.
