This lovely silver-tone and light blue rhinestone necklace and screw back earrings set is signed, "Coro" on the earrings, and was made in 1954 and designed by Adolph Katz. The necklace measures 17" long, but can be hooked shorter on its hook and chain adjustable closure. The earrings are 1" across. There is no wear or damage on any of the pieces, but there is a bit of old gray paint on both earring's back loops. I did not try to remove it as it's not distracting.
