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 engineered for gemstone cutting, cabochon shaping, and precision lapidary finishing, delivering exceptional hardness, durability, and flatness. Made from solid zinc alloy, this lap outperforms traditional tin laps by providing fast, efficient polishing across a wide range of stones, including hard gems like sapphire, ruby, corundum, and cubic zirconia.

Application

Its rigid, full-thickness construction allows standalone use without a base plate or master lap. The re-machinable surface maintains long-term precision and predictable consistency. Available in 6" and 8" diameters with 10mm, 12mm, or 15mm thickness, the lap adapts to all polishing stages—scratch removal, pre-polish, and high-gloss finishing. Both professionals and hobbyists can achieve perfectly flat facets and smooth finishes using standard sandpaper and diamond paste.
