What's your favorite type of rock to tumble? Are there ones that tumble well together? Just asking beginner questions, thanks!

Agate tumbles well, yeah. Size matters - you want to have about the same size/hardness rocks together. If they break up in the tumbler, I remove them to run a different batch with smaller ones.

Size does matter....Haha rock tumbling humor right? That's good info, I probably would have been bummed seeing a rock break or think I did something wrong!
