This lovely big butterfly brooch probably dates to the 1940s. It has six big prong-set stones that are set so the light shows through them as real stones are. They aren't painted gold on the back. There is a nice big pink stone in the center and the small stones include two green, one dark blue, on pink and one topaz color. The brooch has a nice gold-tone finish. The pin works fine and the whole thing is in good condition. It is unmarked. This old brooch is about 2 1/2 inches square and fairly lightweight.
