Vintage Large Cameo Brooch Frosted Glass Intaglio

Lovely vintage large cameo brooch featuring a pretty lady in profile in the back of the clear lucite plastic. The cameo is frosted, making a nice contrast with the clear shiny top with faceted edges. Pretty gold tone rope twist type border. Brooch is unmarked but in good condition overall with a few scratches noticeable on close inspection at a certain angle, as shown in last photo. 2" high x 1 3/4" wide.
