We tumble rocks too, and we wanted better grit.
Rockridge Grit is a US shop for rock tumbler media. We sell the grits, polishes, shot and spacers we rely on ourselves, and we build kits around the tumbler you already own.
Results you can see when the barrel opens
The right amount
Bags are portioned for real barrel sizes. You use what's in the bag, and nothing gets wasted.
Clean, graded media
Consistent particle size from step to step, so each grit removes the marks of the last one.
Straight answers
Ask us about your tumbler or a stubborn batch. A person who tumbles will write back.
Three questions, then a kit
Your tumbler
Brand, model and barrel capacity. Rotary and vibratory machines need different amounts and run times.
Your material
Agate, jasper, obsidian, sea glass, brass or sterling. Hardness decides the grit sequence.
Your finish
Satin, high gloss or a burnished shine on metal. We portion each step and write instructions to match.
