Sterling Silver Harmony World Pendant, Chain, and Earring Set

This set is from a teachers collection from the 90's. Was worn frequently for a Geography class. Always a big hit. World pendant is a harmony ball, with a bell inside, marked 925 on the bail. Chain measures 24" long and is Sterling Silver. Earrings were marked on the french hooks, but they have been replaced with new Stainless Steel ones. World are made from Sterling Silver and Brass.
