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 Jubilee cut center diamond is secured within a four-prong cathedral basket that allows light to enter through the open gallery while showcasing the stone's exceptional brilliance. A floral-inspired halo softens the circular outline and creates additional sparkle around the center without overwhelming its proportions.

The split infinity shank flows gracefully toward the halo with micro pavé diamonds following each curve. The intertwined shoulders create elegant movement while maintaining a balanced profile that naturally directs attention to the center stone. Signora Jewels crafts every ring to order in your selected precious metal and center diamond size.
