Description

This precision die cast ring finger gauge set is an essential sizing tool for professional jewelers who demand accuracy at the bench. Constructed from lightweight die cast aluminum, the set covers USA sizes 1 through 15, including half sizes, for a total of 29 individual ring sizers. 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.

When verified with a high-quality digital gauge, the millimeter markings were found to be accurate to within one hundredth of a millimeter — a level of precision that is genuinely impressive for a die cast tool and makes this set a reliable standard for professional ring sizing work.
