Running out of rocks or polishing supplies mid-hobby is the most frustrating interruption to any rock tumbling project. The National Geographic Rock Tumbler Refill Kit gives you everything you need to keep tumbling – 1.36kg of authentic Madagascar rocks (rose quartz, jasper, and more), silicon carbide grit for polishing approximately 4kg of rocks, ceramic tumbler media, and GemFoam for an exceptional final shine. One comprehensive kit, multiple batches of beautifully polished gemstones.
National Geographic quality, trusted by hobbyists worldwide. The refill kit that keeps your collection growing.
What’s in the Kit – and Why Each Component Matters
Rock tumbling is a multi-stage process that requires the right materials at each stage. The silicon carbide grit does the heavy grinding work, progressively smoothing rough rock surfaces. The ceramic media fills space in the tumbler barrel, reducing noise, preventing rock breakage, and improving grit distribution for more even polishing. The GemFoam provides the final polishing stage that gives tumbled rocks their characteristic glass-like shine. The 1.36kg of Madagascar rocks gives you the raw material – beautiful, varied stones that polish into stunning gemstones.
