1950s rhodium plated figure-8 earrings with prong set light and dark marquise faux-amethysts butterfly clip back earrings. Marked "NAPIER PAT. PEND." Measure: 1 1/2 inches long by 1 1/8 inches wide.  Condition: Very good; a little bit of wear to some of the rhinestones' foiling, but since they are a darker color it is only noticeable upon very close inspection. Identical earrings are shown on pg. 239 of  Melinda L. Lewis & Henry Swen's book, "The Napier Co.: Defining 20th Century American Costume Jewelry."
