This 3-pound pack features Madagascar stones in a large 1″ to 2″ range with an average size around 1.25″. The stones are described as brightly colored when cleaned and wet-washed images are used to convey their natural appeal.

The stones are photographed wet to show their natural beauty and are primarily 1 to 2 inches in size. Most stones share similar hardness on the Mohs scale, which supports consistent tumbling results. The mix also includes occasional special stones like Rainbow Petrified Wood and Turritella Fossil Agate, adding visual variety to your polishing project.
Buying Guide
- Stone variety: For beginners, mixes with a broad color range and varying hardness can yield satisfying results, but keep an eye on uniformity for consistent tumbling cycles.
- Size and shape: Irregular, rough stones tend to tumble together more efficiently; larger stones require longer or multi-cycle processing.
- Color and finish: Wet-photos often highlight color; cleaning prior to tumbling can reveal the true hue and clarity of the stones.
- Hardness considerations: Stones with similar Mohs hardness generally produce smoother, more uniform finishes when tumbled together.
- Accessories: Some kits include grit, jewelry findings, or storage pouches—consider these extras when choosing a kit for a complete experience.
- Educational value: Mixed collections can serve as learning tools for geography, mineral identification, and geological concepts.
