Brooch: 3 1/8" x 2 3/8"; fur clip: 2 5/8" x 1 1/2"; earrings: 7/8" diameter
"Sterling Coro-Craft" with Pegasus on back of clip; "Coro Duette STERLING PAT. No. 1798857" on duette mechanism
Design patent D140,602 issued to Adolph Katz in 1945. Utility patent # 1,798,867 issued to Gaston Candas (for clip/brooch mechanism) in 1931 (application filed in 1930).
These two 1940s rose gold-plated sterling silver flowers edged in diamanté with ruby glass stone centers can be worn together as a brooch or as separate fur clips. This Coro Retro Modern Duette— their name for their double clip/brooch — has matching earrings. This versatile set showcases one of Adolph Katz’s brilliant designs from both an aesthetic and engineering point of view. For Duettes that were asymmetrical like this one, the clip/brooch frame had to be customized to work with the particular pair of clips. Truly gorgeous! You can see the utility patent for the brooch mechanism here, shown below Coro’s name. This design was advertised by Coro as Sparkling Peonies.
