IIRC the setup my friend had included a diamond wet saw and various polishing and grinding wheels. For instance I used some wax to stick a rock on the end of a stick and shaped it into a cabochon and, using the various polishing wheels, got it to shine.
A tumbler is just a bunch of rocks and polish bouncing around for a week and you never know what you'll get.
