How to measure at home
- 1String or paper strip. Wrap it snugly around the base of the finger, mark where it overlaps, then measure the length in millimetres — that's your circumference. Match it to the table above.
- 2An existing ring. Measure the inside diameter of a ring that already fits well (in millimetres) and match it to the diameter column.
- 3In person. Collecting by appointment? Bring a ring that fits and we'll size it for you on the spot.
Fingers can vary slightly by time of day and temperature — measure when your hands are at a normal temperature, not right after cold or heat exposure. Complimentary resizing is available on some pieces; check the product page or ask before you buy.
