Reference

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).

This Coro Duette brooch has two rose-gold-plated sterling silver flowers edged in diamanté with ruby-glass-stone centers. It can be worn as a brooch or as separate fur clips, and has matching earrings. Made for Coro-craft, the company’s high-end line, this stunning set showcases one of Adolph Katz’s brilliant Retro Modern 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.
