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 elongated Dutch marquise center is secured by a four-prong cathedral basket that protects the pointed ends while keeping the distinctive outline open to view. A hidden halo sits beneath the center stone, adding brilliance from side angles while preserving the uninterrupted profile of the marquise when viewed from above. The open gallery beneath the basket allows light to enter freely and makes routine cleaning easier.

The micro pavé shank carries a continuous row of round brilliant diamonds along both shoulders, drawing the eye naturally toward the center. The cathedral shoulders lift the setting elegantly while maintaining a balanced profile that is comfortable for everyday wear. Signora Jewels crafts every ring to order in your selected precious metal and center diamond size.

Why is a cathedral basket used?
