The Zinc Polishing Lap is a trusted choice among professional gem cutters and faceting enthusiasts for delivering consistent, high-quality finishes across a wide range of gemstones. Made from solid zinc alloy, this lap offers unmatched flatness, rigidity, and durability—ideal for hard stones like corundum, beryl, quartz, garnet, and cubic zirconia.

Unlike tin laps, zinc laps are excellent for achieving flat facets with less maintenance and longer use life. This lap eliminates the need for a backing plate and can be re-machined for repeated long-term use. Compatible with diamond compounds and oxide-based polishing powders, it offers a tailored pre-polishing experience for every type of gem.

Advantages:

Material & Construction: Solid zinc alloy, no need for a master lap or backing plate. Fully re-machinable for long-term use.

Performance: Excellent for hard gemstones, offering high-gloss, scratch-free finishes.

Versatility: Works with diamond pastes and oxide powders. Reliable pre-polishing solution for various hardness levels.

Preparation Guide:

1. Surface Conditioning: Use 60–80 grit sandpaper to remove initial scratches, followed by 240 grit for smoothness.

2. Polishing Paste: Create a paste with polishing powders and diamond oil. Apply with 50–150 grit sandpaper until darkened.

3. Humidity Control: Keep the surface lightly moist to maximize polish efficiency.
