Cute little Juliana (D and E) figural bug brooch. It is a cast design with blue heat formed plastic wings and a blue cabochon head. It measures just over 2 inches. The metal looks sort of worn in the photo but it really is not, that is just from the texturing to the cast metal.
This bug is a book piece being pictured in my book Juliana Jewelry - The Last Generation on page 99.
