How to find your size

With a ring you already wear: measure its inside diameter, edge to edge, and find it in the chart.
With a jeweller: any jeweller can measure your finger in a few minutes.
With our help: choose "Other" when your size is not listed or you are not sure. Add your size in the order note if you know it. We will contact you and help you find the right size, even for a surprise.

Good to know

Between two sizes, choose the larger one.
Measure at the end of the day, when your hands are warm.
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.

Whether a ring can be resized depends on its design. We are always happy to guide you personally: contact us.
