Silver.
As The majority of the metals I work with, I sand cast, I decided to do the same with a silver bracelet I luckily found in a charity store - However, When melting, I decided not to pour the liquid onto sand - As I would do normally and just allowed the metal to cool in the spoon I was using to melt the metal with. Luckily, this was my outcome after slightly polished.
I didn't know what I wanted to do to this piece but knew I could make the piece even more eye catching. Instead of making an extra hole in the piece, I decided to make use of the ones already there - then allowing me to set the stone in my happy accident.
