Geometric elegance meets vintage purpose in this midcentury gold-filled service award brooch. Made of 1/20 10K gold-filled metal and stamped by the maker “cTo,” this small but substantial pin features a raised floral emblem over a black enamel field, framed by a shield-like, four-point diamond silhouette. Though the issuing organization remains a mystery, the styling suggests a corporate or professional affiliation rooted in midcentury design ideals — clean lines, enamel accents, and modest prestige.
