Ring Sizing Guide

Because every beautiful story deserves the right fit.

Complimentary Ring Sizing

We want your new ring to fit beautifully from the moment you receive it. Complimentary ring sizing is available, so we encourage you to contact us before purchasing. We’ll be happy to help confirm your ring size and advise whether the piece you have chosen can be safely resized.

As a general guide, most of our rings can be resized up to three sizes larger or smaller, although this will depend on the individual design, setting and gemstones.

Please ensure you know your correct ring size before completing your purchase. We are unable to accept returns due to an incorrect ring size once a ring has been purchased.

If you’re unsure of your size, simply contact us before ordering. We’re always happy to help you find the perfect fit.

Simple ways to find your size at home

Option 1. Measure an existing ring

Use a ring that already fits the finger you’re buying for.

  1. Place the ring on a flat surface.
  2. Measure the inner diameter, inside edge to inside edge, in millimetres.
  3. Match your measurement to the chart below.

Option 2. Measure your finger

Use a strip of paper or a piece of string.

  1. Wrap the paper or string around your finger, not too tight.
  2. Mark where the ends meet.
  3. Lay it flat and measure the length in millimetres.
  4. Match that measurement, the circumference, to the chart below.

Tip: measure at the end of the day when your fingers are naturally a little larger, and avoid measuring when your hands are cold.

Option 3. Print our size circles

For the most accurate result, print our sizing guide at 100% (actual size). Before you measure, check the print scaled correctly: the test line on the printed guide should measure exactly 50 mm. Then find the circle that matches your ring’s inner diameter, or cut the circles out and try them on your finger.

Before you print: turn off “fit to page” or “scale to fit” in your printer settings and print at 100%. Then measure the test line on the printed sheet. If it reads 50 mm, your size circles are accurate.
