BUYING GUIDE
Rocks for Tumbling
Good batches begin with suitable starting material. Choose identified stones that can be evaluated for hardness, cracks, texture, and compatibility instead of relying on colour alone.
Before you choose
- Look for a clear material description and a suitable tumbling workflow.
- Inspect for cracks, crumbling areas, deep pits, and mixed hardness.
- Build a size mix consistent with the machine instructions.
- Record the source and keep uncertain or unusual material separate.
THE TRADEOFF THAT MATTERS
Buy for your process.
A beautiful rough stone is not a guarantee of a polished result. Some specimens are more rewarding to keep as they are, especially when they are fractured, delicate, or poorly identified.
