Gorgeous Topaz Onyx and Red Enamel clip outlets on earrings

These beautiful quality clips are signed outlets by the designer but the the stamp is unfamilar to me. They are heavy and dazzling topaz rhinestones encircle a large onyx cabochon. The space is filled with rich red enamel and Indian style gold embellishments. Excellent vintage condition. Some light wear to finish on raised gold embellishments see photos
