Selecting the correct ring size is essential — particularly for bespoke designs featuring multiple stones, as resizing can be limited or, in some cases, not possible.

To ensure the best fit, I recommend following the method below in conjunction with our sizing chart.

Measure a Ring
Use a well-fitting ring and measure the internal diameter (in mm) across the centre using a ruler. This is the most accurate at-home method. If it’s a Surprise, borrow a ring worn on the same finger of the opposite hand — it’s often a close match.

For best accuracy, visit a local jeweller for professional sizing. Finger size can fluctuate so we recommend measuring at the end of the day when hands are warm.
