From what I can find this brooch appears to be c. 1930's Art Deco Rhinestone Brooch, Pot Metal, approximately 2”. Layered bands of pave rhinestoines make up this brooch. Very elaborate for it's time. I’ve wiped it down but it could use a good cleaning from someone skilled at working on these old pieces. It is in beautiful vintage condition with some yellowing of some stones. The pictures are the best description of this lovely Art Deco brooch. It has a gorgeous ribbed caged looking silver tone metal that is 3 dimensional with clear rhinestones and an ornate period design. Truly lovely! Great find for collectors!!
