Rock tumbling generally takes 4-5 weeks in a minimum 4-step process. Part of that procedure is wearing away the hard edges of a rock through continuous tumbling inside a rubber-lined barrel with water and a selection of abrasive grits. The final stages of the tumbling include a washing cycle, followed by one using a polishing powder and tiny plastic pellets.
Some rocks may not turn out so well due to their porosity and for other reasons unknown to me. For example, in the upper photo, the largest dark gray stone with a light gray band did not turn out as we expected. It may find its way back for another tumble.


And at some point I may take a few of my favorites and have them made into pendants. Do you see the agates?
