The short answer

How long does it take to tumble a rock?

The standard rock tumbling process typically takes 4 to 6 weeks. This involves four distinct stages: coarse grinding (1 week), medium grinding (1 week), pre-polishing (1 week), and the final polish (1 week), plus cleaning time between stages. Factors like rock hardness and desired shine can extend the final stages.
