Get professional rock polishing results with this Lortone double-barrel rock tumbler and deluxe rock tumbling kit!

You'll end up with agate, chalcedony, jasper, rose quartz, and more that have a sleek, smooth finish. This quiet, durable tumbler can hold up to 6 pounds of rock (3 pounds in each barrel) for quantity tumbling. The set has everything you need to get started: the Lortone 33B rotary rock tumbler, 2 pounds of select tumbling rock mix, enough 4-stage grit to tumble and polish 12 pounds of rock, and rock tumbling instructions.

The rock tumbler features patented rubber barrels with a quick-seal cover and a powerful continuous duty electric motor. The tight-sealing rubber barrel not only produces beautifully polished pieces but provides extra sound absorption for quieter operation. This tumbler is capable of running 24 hours per day for years. A rotary tumbler has the advantages of removing all the rough edges to produce nicely rounded corners and also is suitable for tumbling hard minerals. It typically takes 4-6 weeks to completely polish a batch of rocks. One year warranty from Lortone.
