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.

A 1.50 ct, 11.95 × 5.91 mm marquise center is framed by marquise and round accents totaling approx. 0.82 ct. Approx. 2.32 ct total.

Choose your center weight and metal for this made-to-order ring.

Signora Jewels sets the 11.95 × 5.91 mm marquise inside a pointed halo built from alternating marquise and round diamonds. The larger marquise accents read like leaves around the center, while smaller rounds fill the spaces between them and continue into the diamond-set shoulders.

The center sits approximately 7.0–7.5 mm high, leaving an open gallery beneath the cluster. At the base, the band measures about 2.00 mm wide and 1.70 mm thick, keeping the lower shank controlled beneath the wider halo.

The marquise halo stretches the design vertically instead of building a round border around the center. Its pointed leaf shapes repeat the center outline, while the round accents fill the smaller gaps and carry sparkle outward into the shoulders.

About Lab Grown Diamonds

The marquise center puts much of its visual spread along the finger, while the surrounding marquise accents repeat that pointed geometry on a smaller scale. Read more about elongated shapes in the diamond stone guide.

Metal, Care & Fit

White gold and platinum make the halo read as a brighter continuous frame; yellow and rose gold create more contrast around the separate leaf-shaped diamonds. Compare choices in the metal guide. Clean beneath the open gallery and around the halo with warm water, mild soap and a soft brush.

FAQ

What makes this halo different from a standard round halo?
The halo uses marquise diamonds as pointed leaf-like accents around the elongated center. That repeats the shape of the main stone instead of creating a circular border.

How much diamond weight is in the halo and shoulders?
The complete accent setting totals approximately 0.82 ct. Marquise accents contribute approx. 0.42 ct and round accents contribute approx. 0.40 ct.

How high does the marquise center sit?
The setting rises approximately 7.0–7.5 mm. That leaves an open gallery beneath the halo and gives the elongated center visible separation from the shoulders.

Will this ring sit flush beside a straight wedding band?
The wide halo and elevated gallery can leave a small gap beside a straight band. A contoured band follows the pointed cluster profile more closely.

How should the halo be cleaned?
Use a soft brush around the marquise tips, between the smaller round accents and beneath the open gallery. Those recessed junctions collect more residue than the plain lower shank.
