Saphiret barrette, rock crystal, buying France, vintage,

This is a nice barrette in good condition marked, 'MADE IN FRANCE'. In the center is a saphiret, next to that are two faux pearls and next to thonse are two rock crystals. The length of the decorated top is 2" and the width is about 1/4". The back is silver tone and there are a couple of very small rust spots, the front is in very good condition. buying I am wondering if at some time the barrette part was replaced on this.......
