Your first batch has been tumbling for a full week now, and the rocks sitting in the barrel still look exactly like dull gray rocks.

Most beginner instructions hand you a grit number and a countdown, then stop. They rarely explain why an underfilled barrel produces flat spots, why leftover coarse grit ruins a polish two stages later, or why a soft stone tumbled beside agate simply wears away to nothing. None of that is a beginner mistake. It is missing information.

What Four Correct Stages Produce

  • Sort rough stone by Mohs hardness so nothing in the barrel destroys itself
  • Run all four grit stages, start to finish, without a single contamination guess
  • Read a hazy Stage 4 result and know within minutes exactly which stage failed
  • Build working grit schedules for agate, jasper, quartz, petrified wood, and obsidian
  • Catch flat spots, pitting, and barrel leaks before any of them cost you a batch
  • Label, display, and photograph a finished collection that looks worth keeping
