Antique Mother of Pearl Brooch Art Nouveau Edwardian Art Deco Gold Filled

Antique Mother of Pearl & Rhinestone Brooch Edwardian, Art Nouveau, or Art Deco 10k Gold Filled or Plated. This was so tarnished and was thought to be sterling. Once cleaned up, it was obviously a gold tone with some silver tone visible. I acid tested the gold, and it seems to have some reaction with the 10k gold acid as it was not completely dissolved. It dissolved for the 14k, so that test was negative. I’m not sure if this is sterling underneath, or some other metal since it’s hard to get to the silver to test it alone. It’s not magnetic. The pin works. Very cool piece to add to your collection. See photos and video if available for exact condition.
