Leather Laps – Final Polish Laps for Soft & Medium Hardness Gemstones

Leather polishing laps provide a gentle, compliant polishing surface ideal for achieving a bright final polish on soft to medium hardness gemstones. The natural leather surface works exceptionally well with cerium oxide, alumina, and tin oxide compounds, making it the preferred choice for opal, turquoise, feldspar, and other stones in the Mohs 4–7 range.

Frequently Asked Questions

• Q: Why use a leather lap instead of a metal lap for final polish?
  A: Leather’s natural compliance allows it to conform slightly to the stone surface, reducing the risk of scratching and producing a bright, even polish on softer or more delicate gemstones. Metal laps are better suited for hard stones requiring precise flat facets.
• Q: What polishing compound works best on a leather lap?
  A: Cerium oxide is the most popular choice for leather laps, particularly for opal, feldspar, and glass. Alumina and tin oxide also work well for a range of soft to medium hardness stones.
• Q: Can I use a leather lap for opal?
  A: Yes. Leather laps with cerium oxide are widely regarded as one of the best combinations for polishing opal, producing a bright, high-clarity finish without risking surface damage.
• Q: How do I care for a leather lap?
  A: Keep the leather lap lightly moistened during use. After polishing, allow it to dry naturally and store flat. Avoid soaking or exposing to excessive heat, which can cause the leather to warp or crack.
• Q: What sizes are leather laps available in?
  A: Leather laps are available in standard 6-inch and 8-inch diameters. Browse Leather Laps →
