Vintage Coro Gold Yellow‎ Rhinestone Brooch

Gently used vintage Coro brooch. It is gold tine with yellow rhinestones. It is signed twice on the back, Coro. There is also some script under one of the marks that I can't quite read but I think it says, des pat pend. This would date the brooch back to the 1950's. It is in very good vintage condition with minor scuffs/scratches from use.
