This is such an interesting "sweetheart" necklace, with an unusual open heart pendant that has a ribbon of rhinestones circling one side, and with a large peridot rhinestone tucked behind the ribbon. The pendant has about a 3/4 inch diameter, and the elegant chain is 16 inches long, with a detachable extender adding another 2.5 inches. The necklace comes in its original box, plus the back of the pendant is marked "N R" which is an Avon mark. A really perfect necklace for a sweetheart gift!
