I love these vintage earrings and I date them circa 1940s/50s. They’re fashioned from sterling silver and carved wood. They're stamped on the screw back "sterling". They have the look of the 1950s New York  jewelry artists or perhaps Danish. They measure 1 3/4 x 1/2 inch. They’re very light weight and in very good condition with no problems. I have not polished the silver portion of these earrings.
