This is a gold tone necklace with a bezel set medal pendant celebrating the 500th anniversary of Christopher Columbus' discovery of America. The necklace is not signed and I do not know who made it. The medal has a picture of Columbus on one side with Discovery 1492-1992. On the back is a picture of the Santa Maria and Discovery 1492-1992. The necklace measures 29 inches long. The pendant is 1-1/2 inches long. The necklace and pendant are in very good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
