Vintage 800 Silver Filigree Butterfly Brooch

This beautiful 800 silver filigree butterfly brooch came from an estate with two others. The last photo shows them all together. This one has pointed wing tips and measures 2 3/4" wide by 1 1/2" tall. Pinback has a locking clasp. Weight: 12 grams. Some tarnish. Lovely patina. Likely Mexican.
