Kate Wolf transforms ring sizing with the TRUE-SIZE System


“One of the greatest pleasures in my life is that I get to take my frustrations out on my tools,” says Kate Wolf, bench jeweler, tool designer and lover of all things well crafted.

So what’s her latest frustration? Inaccurate ring sizing.

Trusize-June“I’ve bought every set of sizing rings I could find over the years,” she says. “Not one of them is accurate.” Kate believes that inaccuracy was having a negative impact on customer service (not to mention frustrating bench jewelers the world over).

“When the sizing rings and mandrels are inaccurate it results in compound errors,” says Kate. “Then the customer comes in, she lights up at seeing the beautiful ring you’ve made for her, she puts it on, and is disappointed to have to leave the ring behind to have it resized. It sours the transaction.”

Her solution? Build a precisely calibrated system that is truly accurate, from the counter to the bench and back.

Kate partnered with George Khanduja of Ikohe to design and manufacture the TRUE-SIZE ring sizing system. The TRUE-SIZE mandrels and ring sizers ensure that a size 6 measured with the customer at the counter translates to the exact same size 6 at the bench, eliminating costly resizing efforts, disappointed customers and frustrated bench jewelers with one system.

The TRUE-SIZE set comes in a wood presentation box that displays beautifully on a counter. It contains 47 stainless steel sizing rings that look and feel like real rings and an aluminum sizing mandrel that is clearly etched in quarter sizes.

Two steel mandrels, one grooved and one smooth, complete the system. They are also etched in quarter sizes and are perfectly calibrated to the counter set, so bench jewelers can form with confidence and create the right size the first time.

“I have no doubt that the TRUE-SIZE ring sizing system will be on the counter of jewelry shops all over the country in no time and will replace all other mandrels in the workshop,” says Kate.

The complete TRUE-SIZE system is available at RioGrande.com.
