Ring size guide

Lay a ring you own flat on the circle and slide until it sits just inside it — or set its inner diameter directly.

Measure the inside of a ring that already fits — inner edge to edge — with a ruler in mm, then set it below. No ring handy? Try Measure your finger.

Between sizes? Always choose the larger size. Fingers are slightly bigger in the evening — measure then for the best fit.

Method 1 — Use an existing ring

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

Method 2 — Wrap and measure

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

Tip: Middle finger sizes typically run half a size larger than the ring finger. If between sizes, go up. Measure in the evening — fingers are slightly larger then.

The clean corners of a princess-cut diamond give this ring a crisp, modern look. Four rounded prongs hold the stone securely while leaving the sides open so light reaches the pavilion.

The crossed shoulders sweep beneath the center and meet in a soft twist before flowing into a smooth comfort-fit band. From the side, the open gallery keeps the setting light without taking attention away from the diamond.

Select a center diamond from 1 to 4.5 carats and choose your preferred metal. Every ring is made to order by Signora Jewels so the setting stays balanced for the diamond you select.
