To ensure your 18K gold heirloom feels as perfect as it looks.
Enter your finger circumference in millimeters (mm)
1. Wrap a thin strip of paper or string around the base of your finger.
2. Mark the spot where the ends meet.
3. Measure the length with a ruler in millimeters.
4. This measurement is your circumference (use the tool above).
Measure the internal diameter of a ring you already own that fits the same finger. Multiply that diameter by 3.14 to get your circumference.
