True-Size Ring Mandrels

True-Size Ring Mandrels

After years of frustration coping with sizing errors resulting from the use of inaccurate ring mandrels, a jeweler contracted with Ikohe to design and manufacture a ring mandrel that is truly accurate. The result of that collaboration is the True-Size Ring Mandrel. Constructed from hardened steel, each mandrel is laser etched with US sizes 1 to 16 in 1/4 size increments. A second scale for measuring shank lengths is also laser etched onto the mandrel. Choose between graduated style or grooved and graduated style. Overall length 13".
