Frequently Asked Questions

• Q: What diamond compound grit should I use on a tin polishing lap?
  A: Use 14,000–80,000 grit diamond compound on a tin lap for the final mirror polish stage. Start with 14,000–30,000 grit to remove any remaining pre-polish scratches, then finish with 50,000–80,000 grit for the final water-clear mirror surface. Apply a tiny amount of compound — a little goes a long way on tin laps. Work at consistent speed with very light pressure.
• Q: Why is tin the preferred material for final polishing laps?
  A: Tin's soft, malleable surface allows ultra-fine diamond particles to embed slightly into the lap, creating a consistent, controlled polishing action that produces the brilliant mirror finish required for faceted gemstones. Tin is soft enough to conform slightly to the gem facet surface, ensuring even contact and consistent polish across the entire facet. Harder metals like zinc or copper are too aggressive for final mirror polishing.
• Q: Do I need a zinc pre-polish lap before using a tin polishing lap?
  A: For hard gems (Mohs 7+) transitioning from 600–1200 grit diamond laps, a zinc pre-polish stage with 3,000–14,000 grit compound significantly improves final polish quality by removing residual scratches. For softer gems and when using fine pre-polish grits (1500–3000) on diamond laps, you can often transition directly to the tin lap. Always inspect the gem surface under 10× magnification before switching to the tin lap — no visible scratches should remain.
• Q: How do I charge a tin polishing lap with diamond compound?
  A: Apply a tiny amount of 14,000–80,000 grit diamond compound to the tin lap surface — a pea-sized amount is sufficient for a full polishing session. Spread evenly with your finger or a soft cloth. Run the lap at low speed for 1–2 minutes before polishing to work the compound into the tin surface. Reapply only when polishing action noticeably slows — over-applying reduces effectiveness.
• Q: How do I maintain and store tin polishing laps?
  A: Rinse tin laps with clean water after each use and dry thoroughly to prevent oxidation. Store in a clean, dry location away from contamination. Dedicate your tin lap exclusively to final polish compound — never use it with coarser grits. If the tin surface becomes contaminated with coarser grit, the lap must be thoroughly cleaned or resurfaced before use. Tin laps can be resurfaced by lapping flat on a glass plate with fine abrasive if the surface becomes uneven.
