This pin/brooch is about 3" by 2" . The front looks gold since the markings ay sterling the piece has Gold Plating over the Sterling. The large Stone 1' by 3/4" has the color of a Topaz, but may be glass as it is mounted in sterling. Whatever else it is its a very attractive pin and would be a handsome accessory.
