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 dress clips, and has matching earrings. Made for 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 brooch frame had to be customized to work with the particular pair of clips. Truly gorgeous pieces in remarkable condition! You can see the utility patent for the brooch mechanism here, shown below Coro’s name. This design was advertised by the company as Sparkling Peonies.
