6"x1/2" Solid Zinc Polishing Lap – 12mm Gemstone Faceting and Polishing Lap, Durable Zinc Alloy

The Zinc Polishing Lap is a professional-grade faceting lap designed for gemstone cutting, cabochon shaping, and precision lapidary finishing, offering unmatched hardness, durability, and flatness. Made from solid zinc alloy, this lap is harder than traditional tin laps, delivering fast, efficient polishing on a wide range of stones, from hard gems like sapphire, ruby, corundum, and cubic zirconia to softer varieties. Its rigid, full-thickness construction allows independent use without a base plate or master lap, while its re-machinable surface ensures long-lasting precision and consistent results. Available in 6" and 8" diameters with 10mm, 12mm, or 15mm thickness, the lap provides versatility for all polishing stages, from scratch removal to high-gloss finishing. Professionals and hobbyists can achieve perfectly flat facets and smooth finishes by following simple polishing steps with sandpaper and diamond paste, making this zinc lap a reliable, long-term solution for gemstone faceting, cabochon polishing, and lapidary excellence.
