This is a Victorian style bar pin brooch. It has a large dark green rhinestone in the center and two small imitation pearls. The rhinestone is a darker green than it appears in my pictures. The brooch has an antiqued gold tone finish. It is not signed and I do not know who made it. The brooch measures 1-3/4 inches by 1 inch. It is in very good condition and appears to have been gently worn. Please let me know if you have any questions. Thanks for stopping by.
