These are a pair of Silver & Abalone Shell Screw On Earrings. They must have been a favorite of the previous owner as they invested in having one of the Earrings repaired. The screw on post is different on each earrings and one was professionally replaced. They measure 1" long x 5/8" and are crafted in 3 parts wing shapes with Silver enclosed in the 3 parts and all around the Earrings. These Earrings date from the 1930's - 1940's and are Mexican Silver and definitely are Sterling. They are not marked, may have been marked before the screw on posts was attached to the back.
