What it does

This solid metal sizing stick allows for accurate measurement of US ring sizes, from half to full sizes, with clearly engraved lines.

The flared handle provides a comfortable and secure grip, essential for consistent application during sizing operations.

How to use it

  • Select the correct US size marking.
  • Slide the ring onto the mandrel for measurement.
  • Wipe clean after use to maintain markings.

Who it's for

Bench jewellers, silversmiths, and ring makers creating or resizing for US clients will find this indispensable. It replaces guesswork and replaces less precise methods, ensuring accurate fits for both custom orders and customer adjustments in a retail setting.

William R. ★★★★★

I've been using this mandrel every day for a week and the US size markings are spot-on, which saves me so much guesswork when resizing customers' rings. The metal is hefty enough that it doesn't wobble on my bench, and the dull finish actually helps me see the sizing lines clearly without glare.

Edward I. ★★★★★

I’ve used it to size a few rings for friends and the US markings are dead-on accurate, which saves me the guesswork. The metal is hefty enough to stay put on my bench, so I don’t have to worry about it sliding mid-measurement.

Kevin H. ★★★★★

The dull finish is honestly a nice touch—rings slide on smoothly without scratching, and the etched US sizes are sharp and easy to read. It’s solid enough to hold steady even when I’m tapping a stubborn band down, which makes sizing both men’s and women’s rings a quick job.
