These Estate Solid 14K Yellow Gold Diamond Stud Earrings are a stunning vintage piece for women who appreciate fine jewelry. They have a beautiful wing shaped design. Since i couldn't locate hallmarks, these have been fully tested by my jeweler and came back as solid 14k gold with natural diamonds. They measure just over 5/8" tall by just under 1/2" wide. These are nice clean diamonds with life and sparkle. These weigh in at 3.5 grams
