This vintage navy blue Coro Thermoset necklace and bracelet set date from 1956. I have included a picture of a 1956 spring/summer magazine advertisement featuring this set in pink. In the vintage ad the set is called Moonray. It is a silver metal set with navy blue Thermoset plastic squares. The bracelet is in like new condition and appears to have never been worn. It measures 7 ¼ inches with a fold over clasp and has its original safety chain. The necklace has minor metal wear to the underside and is adjustable with a hook and tail closure from 13 to 17 inches. Both pieces are marked Coro on the reverse.
