Vintage crystal encrusted rose brooch and pendant, marked PWC, almost 2.5"across

This is a lovely brooch and pendant (see photos) of a rose. It is signed PWC. Gold tone color is perfect, no discolorations. Item stored for decades. Probably never worn? The crystals are bright and lively. Very well made. No crystals missing. The brooch is almost 2.5" across. Great bling, great price.
