David Yurman Pearl Stud Earrings - Cultured Freshwater Pearls and Diamonds in a Sterling Silver Setting. As shown, the setting of the earrings and the earring backs are stamped DY and 92.5 (sterling silver) and the posts are stamped DY and 585 (14K gold). These earrings are in Perfect, Like-Brand New Condition as I’ve hardly ever worn them given I tend to wear the same few earrings repeatedly, rarely wearing pearls. I purchased these from our local DY authorized jeweler, B.C. Clark Jewelers. Comes with the DY drawstring pouch and the unused polishing cloth. Very pretty and feminine and a great size to wear for everyday!
