The shield-shaped motif of modified wreath design, set in the center with a kite-shaped emerald weighing approximately .75 carat, completed by 77 old European-cut and rose-cut diamonds weighing approximately 2.50 carats, mounted in silver and gold, signed Tiffany & Co. With fitted leather box signed "Tiffany & Cie, 56 Avenue de l'Opera, Paris."
