Circa 1980s, 18k, Switzerland. These diamond hoop or circle earrings are the consummate show stopper. Set with 15.80 carats of brilliant white diamonds (F color, VS clarity), the center diamonds are 1.15 carats each and can be worn separately. Big and bold, the look is all about white diamonds, yellow gold, and size. Made in the highest quality … that is what we love about Swiss jewelry. Excellent condition.
