Antique Victorian Mother of Pearl & Gold Ornate Brooch

This is a beautiful antique Victorian brooch. Carved mother of pearl open rectangle with high karat gold cast ornate nouveau flourishing corners. This is a very collectible and old brooch from the 1800's. Brooch closure is a C hook, I believe it is brass. There is a small crack in the mother of pearl on the bottom right side. Very collectible and rare.
