Ring Size Guide

Our rings are made to be worn every day, so the fit matters. Here are three simple ways to find your size.

With a ring you already wear

Measure the inside diameter of a ring that fits the same finger, edge to edge, in millimetres, and find it in the chart below.

With a local jeweller

Any jeweller can measure your finger in a few minutes.

With a ring sizer from us

If you are unsure, choose "Other" when you order. We will send you a ring sizer and craft your ring once your size is confirmed.

Good to know

Between two sizes, choose the larger one.
Measure at the end of the day, when your hands are warm. Fingers are smaller in the cold.
Wider bands fit more closely, so you may prefer half a size larger.
Eternity rings cannot be resized, as the stones go all around the band.

Resizing

Whether a ring can be resized depends on its design. Contact us and we will advise you.
