A rock tumbler transforms what looks like plain rocks into beautiful gem-like stones once they are polished to a high-luster shine! They make great pieces for collections or jewelry-making. Rock tumbling kits are popular gift items for kids and adults, and include a tumbler, tumbling rock mix (including semi-precious stones), and polishing grit. The Lortone tumblers with patented rubber barrels provide professional-looking results and have a 1-year warranty. Refill supplies are also available.
