Sterling Wirework Pierced Earrings: Although these have no marks, we believe they are sterling. They do appear to be hand made. The wirework in the "petals" is not completely uniform. They are in very good condition.We left the patina (did not clean them) because many people, me included, prefer this to the brilliant shine. They should clean up to a bright shine. They measure approx. 1" across. The shipping fees quoted are for first class/No insurance in USA only.
