Vintage Signed Christian Dior Round Gold Tone Brooch or Pin

Pretty pin or brooch that features a shamrock in the center with a pretty filigree design. The pin belonged to my mom and I believe she got it as a gift in the early 80s from where she worked. The pin is fully marked on the back. Very minor wear noted but overall in great shape as she hardly wore it. The pin on the back opens and closes with no issues. Measures about 2" wide by 2" high. Shipping in a gift box. Perfect for a jacket etc. Also, makes a lovely gift to someone special. If you have any questions or need additional photos, please let me know. Thanks,
