Things to Consider
- Finger size can change throughout the day due to heat, activity, or hydration. Measure when your hands are at a comfortable, normal temperature.
- If your knuckle is larger than the base of your finger, choose a size that fits comfortably over the knuckle while still feeling secure at the base of your finger.
- Wide bands generally fit more snugly and may require sizing up.
- If you are unsure of your size, we recommend visiting a local jeweller for the most accurate measurement.
