This precision die cast ring finger gauge set is an essential sizing tool for professional jewelers who demand accuracy at the bench.

The reverse side of each sizer is marked with the corresponding diameter in millimeters, ranging from 12.45 mm to 28.83 mm, giving you an immediate metric reference without additional calculation.
