This lovely 18 Inch necklace with many 3 MM prong set round rhinestones but what really set this necklace apart are the beautiful emerald cut (rectangular) glass rhinestone. Four are 1/4 inch long and 2 are 3/8 inch long. This vintage piece is in very good condition. There is one stone that appears to have darken over age but does not distract from the beauty of this elegant necklace. The snap closure is very secure. This wonderful sparkling necklace is an eye catcher.
