This piece is new old inventory, unused, and dates to the 1970's. Suitable for engraving. The two tone pendant measures about 1 3/8" in diameter. Yellow gold filled frame with a florentine finish center disc. The silver disc is not marked, but I believe it is rhodium finished sterling silver-this maker was noted for not stamping his silver pieces properly. The back has a bit of tarnish or discoloration. The 24" rope chain has a spring ring catch and is marked "12kgf A&Z", indicating a gold filled finish from the A & Z Hayward Company.
