My pick is that these are above sterling frogs on the bracelet and earrings. The bracelet is 6 3/4" long and closes with a hook. The width is 3/4". The screw back earrings are 3/4". The marking is 0.980 on the bracelet. The earrings are marked 980 Taxco. The pieces were made before 1948. The set weighs 1.8 ounces. Excellent vintage condition.
