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 hidden halo engagement ring from Signora Jewels.

A 2.00 ct, 13.10 × 7.02 mm marquise center sits in a Four-Prong setting above round accents totaling approx. 0.17 ct across the shoulders and hidden halo. Approx. 2.17 ct total.

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

Signora Jewels sets the 13.10 × 7.02 mm marquise between curling engagement ring shoulders that pass around the center like vines. Round diamonds punctuate the leaf forms, while a Hidden Halo sits beneath the marquise instead of surrounding its face.

The Four-Prong basket rises approximately 7.0–7.5 mm and leaves the gallery open from the side. At the base, the shank is about 1.60 mm wide and 1.50 mm thick, keeping the lower band fine while the shoulder work spreads to roughly 4.5–5.5 mm.

The Hidden Halo is deliberately below the center line. From above, the long marquise stays clean from tip to tip; from an angle, the smaller diamonds appear beneath the basket and through the curling shoulders.

About Lab Grown Diamonds

The 13.10 mm marquise puts much of its visual spread along the finger, while the smaller rounds add light below and beside the center without interrupting its pointed outline. Read more in the diamond stone guide.

Metal, Care & Fit

White gold and platinum keep the Hidden Halo visually close to the center, while yellow and rose gold make the sculpted vine work more pronounced. Compare options in the metal guide. Clean beneath the raised basket and through the open shoulder curves with warm water, mild soap and a soft brush.

FAQ

Where is the Hidden Halo on this marquise ring?
The Hidden Halo sits below the face of the marquise, underneath the center setting. It adds side-view sparkle without forming a visible border around the center from directly above.

How much accent diamond weight does this design have?
The round shoulder and Hidden Halo diamonds total approximately 0.17 ct. The listing uses the confirmed total weight without relying on an estimated stone count.

How are the pointed ends of the marquise protected?
The Four-Prong setting supports the elongated center at its exposed ends and sides. The 13.10 × 7.02 mm outline remains open enough to read clearly from above.

How high does the center sit?
The setting rises approximately 7.0–7.5 mm. That creates the open space needed beneath the center for the gallery and Hidden Halo.

Will this ring sit completely flush with a straight wedding band?
The Bypass shoulders and elevated basket can leave a small gap beside a straight band. A contoured band follows the sculpted profile more closely.
