A Youtuber named HeyJesse recently made a video saying that her Cartier Panthere bracelet broke. She said she took her pieces in for cleaning, and they came back with black residue appearing on her skin. Shortly after, she was taking off her Panthere bracelet and it snapped/cracked in two. I find it hard to believe that a routine jewelry cleaning caused this, but this is what she is thinking happened. I’m curious if anyone else has had issues with pieces weakening after cleaning or breaking in two.
