This Hi-Tech Diamond 6″ digital caliper is accurate to /-.01mm, measures inside and outside diameters, and can be quickly toggled between inches and millimeters. Calipers make precise measurements of beads, gems, cabochons, bezels and mounts.

Hi-Tech Diamond 6" digital calipers are professional quality, with hardened-steel jaws and prongs. Why does hardened-steel matter? Non-hardened jaws and prongs will eventually indent or become abraded resulting in measurement inaccuracies.  Slots are ground and polished, not merely milled out, for a smoother sliding motion. Each and every caliper goes through a 15-point accuracy test.
