Mixed pieces in a tumbler

Wanted to ask for any tips on what I can put in a tumbler at the
same time? My pieces are silver and finished to a high polish. I have
different styles of rings but they all have quite sharp/acute edges.
Can I mix them together? Also, any thoughts on mixing bangles and
rings together? Again, everything has a hard edge.

Thanks for your advice in advance.

You can mix things. Don’t put herringbone chains in a rotary tumbler.
