Although these pierced earrings are not signed, I did have the matching necklace with the signature "Oscar de la Renta". These stunning earrings are set in a gold tone metal finish. The top has marquise crystals on one side and round crystals on the other. The drop has a large round crystal surrounded with smaller crystals and a marquis crystal on each side …then a huge teardrop yellow crystal at the bottom. They measure 2-1/2" long x 3/4" wide. They are in excellent condition.
