Ring size guide
Our signet rings use European sizes, which equal the inner circumference of the ring in millimetres. Open rings adjust gently to most sizes.
How to measure
- Wrap a thin strip of paper around the base of your finger.
- Mark where it overlaps and measure the length in millimetres — that is your EU size.
- Measure at the end of the day, when fingers are slightly larger. Between sizes? Choose the larger one.
