This is a Victorian stamped gold tone brooch. It has 8 light colored and 1 dark colored prong set amethyst rhinestones. There is also applied filigree and a flower. The brooch is not marked. It does have a C clasp. It measures 2 inches wide and 1-1/8 inches tall. It is in good condition but there is a spot of something dark by the bottom center rhinestone. I have not tried cleaning it. Please let me know if you have any questions. Thanks for stopping by.
