Circa 1960s Modernist sterling silver ball wrap clip earrings. Marked "Napier Sterling." I believe they are rhodium plated sterling since there is not even a hint of tarnish. Measure: 1 inch long by 13/16 inches wide. Excellent condition. Identical earrings are shown on pg. 763 of Melinda L. Lewis & Henry Swen's book "The Napier Co.: Defining 20th Century American Costume Jewelry." Condition: Very good; light scratches.
