Tumbling square silver sheet

I make pendants out of small squares of sheet silver. I currently
sand and polish each one by hand and with a dremel tool. I have a
tumbler and it seems to me that I could save lots of time by using it
to both smooth my corners and to polish the pieces. What are thoughts
on this? And what steps would I use? I’m completely unfamiliar with
tumbling – it’s a very new process to me and I’ve not even finished
my first batch of stones yet.

Thanks!
