Frequently Asked Questions

• Q: What tools do I need to make a lapidary cabochon?
  A: A complete cabochon set requires: coarse grinding wheel (80–220 grit metal bond), fine grinding wheel (600 grit resin), pre-polish wheel (1200–3000 grit resin), and a final polish compound on a leather or felt lap. A cab machine provides the arbor system to run all stages.
• Q: What is the difference between grinding and polishing in lapidary?
  A: Grinding uses diamond abrasive wheels or discs to shape and smooth the stone surface. Polishing uses fine compounds (cerium oxide, diamond paste) on soft laps to produce the final high-gloss mirror finish.
• Q: Can I do lapidary grinding and polishing without a cab machine?
  A: Yes — flat lap machines, angle grinders with flexible discs, and hand sanding with diamond sheets can all be used for lapidary grinding and polishing without a dedicated cab machine.
