Frequently Asked Questions

• Q: What tools do I need to make a lapidary cabochon from start to finish?
  A: A complete cabochon sequence requires: sintered grinding wheel (80–220 grit) for rough shaping, resin soft wheels (60–600 grit) for dome shaping, expandable drum with sanding belts (120–1200 grit) for surface smoothing, diamond smoothing pads (3000–8000 grit) for pre-polish, and cerium oxide or diamond compound on a felt lap for final mirror polish.
• Q: What is the difference between grinding and polishing in lapidary?
  A: Grinding uses diamond abrasive wheels, discs, or belts to shape and smooth the stone surface — removing material to create the desired form and surface finish. Polishing uses fine compounds (cerium oxide, diamond paste) on soft laps (felt, leather, polyurethane) to produce the final high-gloss mirror finish without removing significant material.
• Q: Can I do lapidary grinding and polishing without a dedicated cabbing machine?
  A: Yes — a standard bench grinder with diamond wheels and a flat lap machine can replicate most cabbing machine functions. Angle grinders with flexible diamond discs, expandable drum wheels, and hand sanding with diamond sheets can also be used for cabochon work without a dedicated machine.
• Q: What grit sequence should I use for a complete cabochon?
  A: A standard sequence: 80 grit (rough shaping) → 220 grit (dome refining) → 600 grit (surface smoothing) → 1200 grit (fine smoothing) → 3000–8000 grit (pre-polish) → 14,000–50,000 grit (near-mirror) → polishing compound on felt (final mirror). Adjust based on stone hardness — harder stones (Mohs 7+) benefit from more pre-polish stages.
