Vintage Jackie Kennedy necklace. This is excellent condition, a really beautiful piece. A gold tone necklace, 17 inches plus a 3 inch extender. The pendant is a cross, stamped 'JBK' (Jacqueline Bouvier Kennedy). It is composed of gold tone and I believe Swarovski crystals (they were the norm in this collection). The crystals are blue. The cross has a length of just over 1.5 inches. Comes in a Camrose and Kross box.
