Ring Size Guide
How to Measure Your Ring Size
- Cut a thin strip of paper or use a piece of string.
- Wrap it snugly around the base of the finger you wish to wear the ring on.
- Mark the point where the paper overlaps, then measure the length in millimetres โ this is your circumference.
- Find your circumference in the table below. We recommend measuring at the end of the day when your fingers are at their largest.
- Between sizes? Choose the larger size โ gemstone rings are easier to resize down than up.
