So sweet 16..So much a part of my youth growing up in the 1960;s. I remember the "Seventeen Magazine" used to advertise prom dresses by Nadine Originals. But only the Prom Queen would wear a necklace set as grown up as this one. The Peter Pan collar in blue rhinestones measures 15 inches around the neck.Thee matching earrings are clip back but any jeweler could convert this set to pierced with little problem. A demur set..any young girl should be thrilled with,. I price realistically but if you love it let me know.I do consider offers.
