Sterling silver earrings with gold tone coating and set with cubic zirconia. Earrings are on posts with screw backs which means half the post is threaded like a screw. I tried to show this in the 4th picture. This picture also has a shadow which looks like tarnish but these earrings are tarnish free. Earrings measure 3/8ths of an inch by 3/8ths of an inch. Stamped 925 and acid tests positive for sterling silver. O
