The 3M PSA Diamond Cloth is a pressure-sensitive adhesive wet/dry abrasive cloth engineered for working with materials rated harder than 7 on the Mohs scale. Micron-graded diamond particles are bonded to a durable cloth backing using a tough resin bond, delivering consistent, high-performance results on hard gemstones, ceramics, and similar materials. The 5-inch diameter and 120 mesh grit make this cloth well-suited for intermediate stock removal and surface refinement in professional lapidary, gem setting, and metalsmithing applications.
