Vintage butterfly brooch gold glittering enameled 3-dimensional 1.25“ x 1.25“

This is an adorable three-dimensional vintagebutterfly brooch. It is unmarked as far as I can see. I do not see any callouts or marks or concerns anywhere on the piece. Please use all up close pictures as a guide as they are part of the description. The front has the four butterfly wings, which are a smooth glittering enamel. They appear very realistic and are in shades of brown, orange, yellow, and green. The body of the butterfly is very detailed with the etching in the thorax and abdomen, and the eyes on top. Thin wires are curled to create the antenna. Would look lovely on a Twilley, scarf, blouse or cardigan. Delicate in size at about 1.25” x 1.25”.
