This is a gorgeous blue set of matching earrings and double strand crystal necklace. The only piece marked is one earring and it is marked Coro. The other earring and necklace aren't marked. Go figure? The necklace measures 18" fully extended. The condition is excellent except there is one rhinestone missing from the clasp. I was tempted to replace the clasp but decided to leave it. The earrings measure 1" in diameter and are in excellent vintage condition. Thanks for looking.
