Coro Duette Patents Each Coro Duette or separable brooch had a uniquely shaped Duette frame made specifically to hold the two pin clips (or fur clips)in a fixed position so that together they could be worn as a brooch. When the duette frame becomes separated from the clips it is almost impossible to know what pin clips it belongs with and the duette is lost to jewellery collectors. Single duette clips can often be found but the value of a separated clip is far lower and less desirable than a fully assembled duette.
