Jewelers, watchmakers, and gemologists use
measuring tools to document, communicate and design. Widely used in so many
trades, these gauges are precision set and ideal for measuring
small parts and designs. Many of the gauges and calipers can measure
the inside diameter as well as the outside diameter using caliper arms that will
reach into small areas. Because of their versatility, these gauges are a great
addition to any workbench: they can measure gemstones, setting sizes,
ring sizes, millimeter size, and so much more.
