Frequently Asked Questions

  • Q: What laps do I need to get started with gemstone faceting?
    A: A basic faceting setup requires: a coarse diamond lap (260–325 grit) for pre-forming, a medium lap (600–1200 grit) for shaping facets, a fine lap (3000 grit full face) for pre-polish, and a polishing lap (tin or zinc) charged with diamond compound or cerium oxide for final mirror polish. A master support lap is also needed for mounting laps on the faceting machine.
  • Q: What is the difference between standard diamond laps and sintered diamond laps?
    A: Standard diamond faceting laps use a resin or metal bond with diamond particles on the surface — economical and effective for most gem materials (Mohs 6–8). Sintered diamond laps have diamond embedded throughout the entire disc — as the surface wears, fresh diamonds are continuously exposed, giving much longer service life on very hard gem materials (Mohs 8+) like sapphire, ruby, and topaz.
  • Q: What are ripple and channel faceting laps used for?
    A: Ripple laps have a textured surface pattern that produces a distinctive ripple finish on faceted gem surfaces — used for specialty decorative faceting effects. Channel laps have grooved channels that provide better coolant flow and a slightly different cutting action — used for specific gem materials and faceting styles where the channel pattern improves cutting performance.
  • Q: What size lap does my faceting machine use?
    A: Most faceting machines use 6" or 8" laps. Always verify your machine's master lap diameter and thread specification (right or left hand, 1/4"-20 or 1/2" thread) before ordering replacement laps or master support laps.
