Frequently Asked Questions

  • Q: Which type of diamond faceting lap should I choose as a beginner?
    A: For beginners, start with standard flat diamond laps — they are the most versatile, widely available in all grits, and compatible with all faceting machines. A basic set of 6" standard laps in 180, 360, 600, and 1200 grit covers most beginner faceting needs. Add a tin polishing lap and diamond compound for the final polish stage. As your skills develop, you can add channel or ripple laps for specific applications.
  • Q: What is the complete faceting lap sequence for a standard gemstone?
    A: A complete faceting sequence: (1) 60–80 grit for initial shaping from rough, (2) 120–180 grit for facet refinement, (3) 220–360 grit for precise geometry, (4) 600–1200 grit for pre-polish, (5) tin or zinc polishing lap with 14,000–80,000 grit diamond compound for final mirror polish. Not all stages are required for every gem — start at the appropriate grit based on your starting material.
  • Q: Are all diamond faceting laps compatible with my faceting machine?
    A: All laps in this collection feature 1/2" arbor holes, compatible with virtually all standard faceting machines including Graves, Ultra Tec, Facetron, Raytech, and most other major brands. Always verify your machine's lap diameter (6" or 8") before ordering. Some machines may require specific lap thicknesses — check your machine's specifications if you have concerns.
  • Q: How do I choose between 6" and 8" faceting laps?
    A: Choose 6" laps for standard faceting machines designed for 6" laps, smaller gem sizes, and when working space is limited. Choose 8" laps for machines designed for 8" laps, larger gem sizes, and when you want more working surface area for consistent facet angles. Always match the lap diameter to your machine's specifications.
  • Q: When should I switch from diamond faceting laps to polishing laps?
    A: Switch to polishing laps (tin or zinc) after completing the pre-polish stage on your diamond laps (typically 600–1200 grit). The surface should be free of visible scratches under 10× magnification before switching to polishing laps. Attempting to polish over visible scratches will result in a poor final finish — return to the appropriate diamond lap grit if scratches remain.
