This very vintage and beautiful Sash Brooch is fairly large North and South 2 1/2 inches and Side to Side it is 3 1/4 inches. Perfect brooch for a heavy jean jacket or coat. This brooch has a simple C closure and it is a shiny gilt color on the back. The faceted Jewel is Purple and is very commanding. Perfect superior brooch. This is very old. I want to say 20's but not sure. To you from Kansas!
