Ring Finger Gauge Square Edge 1-15 USA Standard

A reliable staple for any jeweler's bench, this USA Standard Ring Finger Gauge set provides accurate, at-a-glance sizing across the full range of common ring sizes. The set includes 29 individual rings spanning sizes 1 through 15, including half sizes, making it suitable for everyday customer fittings and professional sizing work.

Each ring is clearly marked on one side with its USA standard size. Half sizes are indicated using a minus sign — for example, size 6½ is marked as 6-. The reverse side of each ring displays the corresponding inside diameter in millimeters, so you can cross-reference USA sizes with metric measurements instantly. Size 6½, for instance, is marked 16.9 for a 16.9 mm inside diameter.

The square-edge profile of these gauges reflects standard ring construction, providing a more accurate fit reference compared to comfort-fit or rounded-edge alternatives. This is an essential bench tool for jewelers, bench technicians, and retail staff who need dependable sizing results in a durable, easy-to-use format.
