Our rings are listed in US sizes 5 to 9. Most designs have an open, gently adjustable band, so a size on either side of yours will usually still fit — but choose your true size for the best look and comfort.

How to measure
- Wrap a thin strip of paper or a piece of string around the base of the finger you will wear the ring on.
- Mark where it overlaps and measure that length in millimeters: this is your circumference.
- Find the closest value in the chart. Between two sizes? Choose the larger one.
Tips
- Measure at the end of the day, when fingers are at their largest, and at room temperature.
- A wide band feels tighter than a slim one; go up half a size for wide designs.
- The quickest check: measure the inside diameter of a ring that already fits the same finger.
