Round Diamond Cluster Signet Ring

Method 1 — Use an existing ring

1. Find a ring that fits the intended finger comfortably.
2. Place it flat and measure the inner diameter (inside edge to inside edge) in mm.
3. Enter that measurement in the Measure a ring tab.

Method 2 — Wrap and measure

1. Wrap a thin strip of paper around the base of your finger.
2. Mark where it overlaps — measure that length in mm (your circumference).
3. Divide by 3.1416 (π) to get your diameter, then use the Measure a ring tab.
