Fabulous old Coro Duette, one of those wonderful and unique brooches that broke down into two clips for alternative fashion use, so clever. This one features sparkly rhinestones set in silver tone metal, with the mounting and mechanism working fine. There are a few tiny missing stones. The brooch measures 2 & 7/8" long; each clip when separated measures a tiny bit shy of 1 & 1/2". Marked on the back Coro Duette and the patent numbers.
