Frequently Asked Questions

  • Q: What is a gemstone faceting machine and how does it work?
    A: A faceting machine is a precision lapidary unit used to cut flat, angled facets onto gemstones at exact angles and azimuths. The gem is mounted on a dop stick attached to a mast or arm that controls the cutting angle. The gem is pressed against a rotating diamond lap to grind each facet to the specified angle, producing the brilliant cuts seen in finished gemstones.
  • Q: What gems can be faceted on a lapidary faceting machine?
    A: Most transparent to translucent gem materials can be faceted — including quartz, amethyst, citrine, topaz, tourmaline, sapphire, ruby, garnet, spinel, and synthetic stones. Hardness 6+ materials are generally suitable; softer materials require finer laps and lighter pressure.
  • 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 (3000–8000 grit) for pre-polish, and a polishing lap (tin or zinc) charged with diamond compound or oxide for final mirror polish.
  • Q: What is the difference between a mast faceting machine and a digital faceting machine?
    A: A mast faceting machine uses a mechanical protractor and index gear to set cutting angles — reliable and widely used by hobbyists and professionals. A digital faceting machine adds electronic angle readouts and motorized controls for higher precision, faster setup, and competition-level accuracy.
  • Q: What size lap does a 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) before ordering replacement laps or polishing discs.
