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.

Signora Jewels sets a 0.50 ct princess-cut diamond between four rounded corner prongs in this halo engagement ring. The reference stone measures approximately 4.4 × 4.4 mm. Small round diamonds follow a softly squared border outside its straight edges.

Design highlights

Fixed 0.50 ct princess-cut center, approximately 4.4 × 4.4 mm

Approximately 18–22 round pavé shoulder diamonds
EF/VS accent diamonds with 0.90 mm and 1.40 mm reference sizes

The round accents soften the outer corners without hiding the princess cut's square face. Two small diamond sizes make up the pavé work, although their individual positions are not specified in the source measurements.

About Lab Grown Diamonds

The princess center has brilliant-style facets within a square outline; the surrounding rounds create smaller reflections around the halo and shoulders. Read our diamond stone guide for more about these cuts.

Metal, Care & Fit

The cushion-shaped head sits above shoulders estimated at 1.85–2.00 mm wide. Brush gently around the corner claws and fine pavé settings, following our jewelry care guide.

FAQ

Is the center a princess cut or a cushion cut?
The center is a square princess cut measuring approximately 4.4 × 4.4 mm. The surrounding halo has a softly rounded cushion-shaped outline, but it does not change the center diamond's shape.

How are the four princess-cut corners secured?
Four rounded polished prongs hold the diamond near its corners. The halo surrounds the center, while the stone's straight edges remain visible between the claws. Avoid hard knocks to the exposed setting.

How much diamond weight is in the halo and shoulders?
The halo contains approximately 0.16 ct of round diamonds, and the shoulders contain approximately 0.12 ct. The 0.28 ct accent total brings the complete ring to approximately 0.78 ct.

Will a straight wedding band sit flush beside this halo?
The reference halo setting is approximately 5.5–6.0 mm high, with shoulders measuring approximately 1.85–2.00 mm wide. Check a companion band against the completed ring to confirm clearance beside the head.

How should I clean the small halo and shoulder diamonds?
Use warm water, mild soap and a soft brush around the four center prongs, the rounded halo corners and the pavé shoulders. Rinse thoroughly and pat dry without pulling fabric through the small metal contacts.
