Coarse grit for one week, fine grit for week two, coarse polish for week three, and fine polish for week four. I've done a few different kinds of stones and I know now not to tumble quartz with anything else because it crushes and mars so easily. It is important to only tumble "soft" rocks (like quartz) with other "soft" rocks, and harder rocks with other harder rocks.
