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 diamond is secured within a refined four-prong cathedral basket that protects each pointed tip while lifting the center stone above the band for exceptional brilliance. The vintage-inspired open gallery allows generous light beneath the diamond while adding elegant side detail.

Fine milgrain edges frame a row of pavé-set round brilliant diamonds along the shoulders, creating delicate texture without distracting from the striking marquise silhouette. The slim comfort shank balances vintage craftsmanship with everyday wearability, giving the ring timeless character from every angle. Signora Jewels handcrafts each piece to order in your chosen precious metal.
