A tumbler will do a NICE job. My friend uses one to polish a lot of small stuff. I do not know what media to use.
My grandson has a "rock tumbler" that I have considered trying to use but its a little late for me
Eastwood offers these tumblers and I would think they have recomendations in their catalog/web site to guide you.
Let us know. I'm interested and curious but spending my time on other things right now. I wish I had bought one in the beginning. I could have saved many $$ that I spent at Ace Hardware!
