For your consideration, I have this Vintage Colorful Rhinestone Brooch for purchase.
The red extra large, emerald cut rhinestone center is a bold and dark red color. The facets within show off flashes of brighter reds as the light reflects on it. The background is gold tone filigree which looks very lacy, there are small blue, green and purple rhinestones scattered around the large center rhinestone. The clasp works as it should and I would say this brooch is in excellent vintage condition.
Measurements: 2" x 1 1/4" - 5.1 cm x 3.2 cm
