Vintage Red Hat Enameled Brooch w/AB Crystals - Large Brooch

Vintage large metallic red hat brooch with a twisted gold tone rim and beautiful aurora borealis crystals. It could be a Red Society brooch or just a pretty red hat brooch. It has a bail and a pin back so it could be worn on a collar chain or other heavier chain. This is a heavier brooch and would be great on a coat lapel but is too heavy for a lightweight blouse. It is also very large, measuring almost 3 inches in length.
