How to Select Rough Rock for Lapidary Work

Choose rough rock by the project, the equipment you have, and the information available in the listing.

Match the rough to the project

For cabochons, carving, tumbling, slabs, or specimens, compare the piece dimensions with the finished size you need and allow room for trimming and grinding.

Check the listing details

• Material name and origin, when known
• Weight and approximate dimensions
• Whether the photo shows the exact item or representative material
• Visible fractures, rind, matrix, or other stated condition details
• Any cutting, polishing, or stabilization already performed

Ask before buying

Natural material varies and a photo cannot reveal every internal feature. If color, pattern, size, or intended use is critical, contact Mayan Knapping before ordering.

Browse rough lapidary material, slabs and specimens, or lapidary equipment.
