This is a wonderful 1930s signed Coro Duette brooch that converts from a brooch into dress clips. The clip patent number dates it to 1932 or later. The silver-tone setting is in good condition with expected age-related wear mostly visible on the back side including some scuffing and scratches. The piece appears to have all original stones. They are clear and sparkly. Brooch and Duette mechanism works well and is secure. No missing stones. The brooch part is marked Coro Duette in script with a patent number on the bottom. The clips just have the clip patent number.
Measures approx 7/8″ x 2 3/8″ wide.
