Warning! Do not tumble rocks containing cracks, crevices, or tiny holes. If you do, it is possible for tiny bits of rock to be released into the batch later on in the process. It can ruin the whole batch by scratching.
Usually go through a range of media sises when polishing. Oils such as kerosene can also be used for polishing. Save the media for the next polish. Try and keep rocks of approximedly the same hardness in each polish batch.
Have lots of patience.
The polish grit "kit" has fine, medium, coarse, and a final polish grit.
