DeLizza & Elster blue cameo pin. This is a book piece and can be found on page 95 of Ann Pitman's Juliana Jewelry Reference book. The pale blue cameo sits atop a darker blue background. The lower layers are set with pale blue and opaque cobalt blue rhinestones. It is set in gold tone metal and in excellent condition. There is one rhinestone that sticks out more than the other and appears to be a manufacturing flaw. It measures 2.25 x 2 inches.
