Gorgeous antique white metal necklace signed P.S.Co. (assuming rhodium plated? Base Metal unknown) The necklace is about 16 inches in length, the pendant is almost 2 inches. It has a beautiful purple glass or crystal accent. It needs to be deep cleaned and some of the jump rings look to be replacements/differ in color. Otherwise is looks like is has barely been worn, considering its age it looks like it could be new! What a beautiful piece of history, se photos for details!
