Vintage Art Deco brooch early plastic pin yellow black clear rhinestones

Vintage Art Deco brooch made of some type of early plastic Three linked circles hang from a bar pin with lots of super sparkly clear rhinestones. My photos don't do justice to the sparkle, it's really pretty in person. Pale yellow and black color It's in good preowned conditon but does have some wear. The rollover part of the safety catch is a little hard to turn, but it keeps in place like it should when you clasp it shut. The bar pin was re-drilled at some point, but not really noticible unless you look close. Meaaures approx 3 1/8" long. Ships fast! HARJ81288JS7H3E
