Modern Solitaire Diamond 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 Size finder 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 Size finder.
