Frequently Asked Questions

• Q: What polishing compound should I use for lapidary cabochons?
  A: The best compound depends on the stone. Cerium oxide works well for quartz and glass. Diamond paste (0.5–1 micron) is best for hard stones like sapphire and topaz. Aluminum oxide suits softer stones like turquoise and opal.
• Q: What lap should I use with polishing compounds?
  A: Leather laps work well with cerium oxide and aluminum oxide. Felt pads suit tin oxide. Ceramic or glass laps are used with diamond paste for hard gemstones.
• Q: How do I apply polishing compound to a lap?
  A: Mix powder compounds with water to a thin paste. Apply a small amount to the lap and spread evenly. Add water as needed during polishing to keep the compound active.
