After inspecting stones for pits, cracks, jagged edges, rough edges, etc., place them in the tumbler. Stones with any of the above will need to be rough tumbled again. Stones that are ready for the next step will have to have filler added if they do not make up 2/3 of the tumbler capacity. Same as Step 1 for abrasives and water. The abrasive should be 220 Grit or 400 Grit, depending upon preference. This should take 6 to 7 days. Check after 24 hours and then every 2 days.
