Antique silver and pink rhinestone brooch

Antique silver and pink rhinestone brooch. Very art nouveau or Edwardian reminiscent design. No material or maker's marks. I was able to shine it up quite a bit with a tarnish cloth so there's a chance of silver, but most likely pot metal. 1 1/8" across. Very good condition. C clasp on back holds a little loose, but it is secure once it's pinned to clothes. You could try to gently manipulate it with some needle nose plyers. Comes from smoke-free home. Offers and questions always welcome.
