Unusual Antique Celluloid Habillé Cameo Brooch

Unique celluloid Habillé cameo brooch! Celluloid mounted in aluminum. Condition: Generally good condition with some wear and imperfection. One can see a very light shadow of what appears to have been more jewels around her neck that are no longer in place. The rhinestones have blackened. While still very secure, the celluloid is pulling away from the mounting a bit on the lower edge. The aluminum metal has a lot of discoloration. The pin back is still in place and still functions well.
