Vintage 4pc Gold Purple Rhinestone Brooch and 50 similar items

Four piece vintage jewelry set in gold tone bows with purple color stones and rhinestones. This is costume jewelry, not fine jewelry. The earrings are screw back so will work for pierced or non-pierced ears. The pendant is also a brooch or a pin, and there is a small loop to thread a chain through to where as a necklace which was common at the time. The chain is not original to the set, it?s an add-on. It barely fits through the loop on the brooch and it looks like it?s squeezed to fit. I?m including it because it still works and why not. Each earring measures approximately 1.25? x 1? the brooch by itself measures 1.75? x 2? and the chain measures 21? end to end.
