Marcel Boucher Parasina Sterling Bow Pin As if tied with real ribbon, sterling silver loops around to create a bow on this darling pin by Boucher. The center of the bow is decorated with three glistening green emerald cut rhinestones. With the rationing of metals during WWII, sterling silver was frequently a substitute for the base metals used in costume jewelry. Companies such as Coro and Boucher went to Mexico to produce some of their jewelry in sterling silver. Parisina was the mark used by Boucher for pieces made in Mexico during WWII. Marked sterling, Mexico, Parisina, measures 2-1/2" by 2". Excellent condition.
