Tumbling / Polishing acrylic or cellulose pieces

Hello! Can anyone help, i’d like to cut some jewelry pieces from acrylic or cellulose acetate sheets and then finish the edges so they look softer / rounder. I know its possible to do this with sanding but I was wondering if its possible to do it in a rotary tumbler? I have so far gathered I should maybe use ceramic media? If someone could point me in the right direction it would be much appreciated! I’m struggling to find any information online.

There are polishing compounds made for this. I always like calling customer service at the various places that I do business. Rio is always especially helpful. Study their catalog and give them a call…Rob
