SURI · THE FIT GUIDE

Find your fit

A little measuring. A better fit.

Use a ring you already love, or measure the finger you plan to wear it on. You’ll need a millimeter ruler and a narrow strip of paper.

Paper strip wrapped around a finger and marked at the overlap
Mark the overlap, then flatten the strip and measure it with a millimeter ruler. Images are illustrative, not actual size.

01 / Measure an existing ring

  1. Choose a ring that fits the same finger and hand comfortably.
  2. Place it flat and measure across the center, from one inside edge to the other. Exclude the metal band.
  3. Match that inside diameter to the size chart.

02 / Measure your finger

  1. Wrap a narrow paper strip around the base of your finger. Keep it close without squeezing.
  2. Mark the overlap, flatten the strip, and measure to the mark in millimeters. This is your finger circumference.
  3. Repeat two or three times, then compare with the circumference column. Check that the fit can pass over your knuckle.
Measure with comfortably warm hands, toward the end of the day. Each finger can be a different size. Wider bands and stacks may feel closer than a single narrow ring.
Between sizes?

Choose the next available size up if the smaller size feels tight. Check this product’s size selector. For the most reliable measurement, use a jeweler’s ring sizer.

    I wasn't looking for matching colors, so I selected our birthstones and hoped for the best. They actually look beautiful together. A little personal detail that makes me happy. 💜

    Pretty ring with a different shape from my usual bands. The two stones are smaller than I expected from the enlarged picture, but the setting is neat.

    Ordered for myself and was pleased with the workmanship when it arrived. The rectangular stones looked neatly positioned and the band had a nice smooth finish.

    Lovely idea, though I prefer the ring on a finger where it has more room beside it. Worn that way it feels comfortable and the design is easier to see.

    The Sera has a bit more character than the single-stone ring I nearly bought. I like seeing the two choices every time I look at my hand. It hasn't felt like a piece I need to reserve for special plans, and it looks really nice with my plain everyday band.
