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 marquise lab grown diamond cathedral engagement ring from Signora Jewels.

A 2.50 ct, 14.15 × 7.21 mm marquise center sits in a Four-Prong Cathedral setting with engraved leaf detailing and no accent diamonds. Approx. 2.50 ct total.

Made to order in 11 metals: silver, 10K/14K/18K gold (yellow, white, rose) and platinum.

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

Signora Jewels sets the 14.15 × 7.21 mm marquise above engraved cathedral shoulders, leaving the diamond completely alone at the center. The split upper shank carries carved leaf forms and fine milgrain borders instead of side stones, so the metalwork frames the long outline without competing with it.

The reference setting rises approximately 7.0–7.5 mm. At the base, the band measures about 1.70 mm wide and 1.50 mm thick, then broadens to roughly 4.5–5.5 mm through the decorated shoulders.

About Lab Grown Diamonds

The reference marquise measures 14.15 mm from tip to tip, putting most of its face-up spread along the finger. With no side stones beside it, the pointed outline stays easy to read. See the diamond stone guide for more on marquise proportions and cut.

Metal, Care & Fit

Yellow and rose gold make the carved leaves and milgrain borders easier to distinguish, while white gold and platinum keep more attention on the center. Compare choices in the metal guide. Clean underneath the raised center and through the engraved shoulder recesses with warm water, mild soap and a soft brush. Browse more engagement rings with elongated centers.

FAQ

Does this ring have any side diamonds?
No. The marquise center is the only diamond; the shoulder detail comes entirely from engraved leaf metalwork and milgrain borders.

How are the pointed ends of the marquise protected?
The center is secured in a Four-Prong setting with support at both pointed ends. The remaining prongs hold the sides while keeping the 14.15 × 7.21 mm reference outline exposed.

How high does the center sit?
The reference setting rises approximately 7.0–7.5 mm. That lifts the marquise above the cathedral shoulders and leaves open access beneath the stone for cleaning.

What makes the shoulders look vintage?
Leaf engraving fills the divided upper shank, with fine milgrain running along the outer edges. The pattern creates texture in the metal without adding another stone shape.

How should the engraved shoulders be cleaned?
Use a soft brush inside the carved leaf recesses and beneath the raised setting. Those narrow grooves collect more residue than the polished lower portion of the band.
