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 cluster engagement ring from Signora Jewels.

A 1.50 ct, 11.96 × 6.06 mm marquise center sits in an elevated Six-Prong setting, with 2 round side diamonds totaling approx. 0.05 ct. Approx. 1.55 ct total.

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

Each metal color is shown in the photos. Choose your center size and metal in the options on this page.

Signora Jewels sets the 11.96 × 6.06 mm marquise vertically, with prongs securing both pointed ends and the sides. Two round diamonds sit lower in the sculpted floral shoulders, while the rest of the detail comes from polished leaves and branching vine metalwork. See more engagement rings built around elongated center shapes.

The center rises approximately 6.5–7.0 mm above an open gallery. At the base, the shank measures about 1.80 mm wide and 1.60 mm thick, then spreads through the 6.0–7.0 mm shoulder area where the leaf forms frame the marquise without closing around it.

The shoulder work stays deliberately open. The two round diamonds give the floral sections a small flash of light, but most of the pattern is carved in metal, so the long marquise outline remains easy to read from tip to tip.

About Lab Grown Diamonds

A marquise cut puts much of its face-up spread along the length of the finger. The photographed 11.96 mm center has a pronounced tip-to-tip outline, while the two smaller rounds add light at the shoulders without interrupting that length. Read more in the diamond stone guide.

Metal, Care & Fit

White gold and platinum keep the prongs visually close to the diamonds. Yellow and rose gold make the carved leaves and open vines easier to distinguish. Compare finishes in the metal guide. Clean beneath the raised center and inside the open shoulder work with warm water, mild soap and a soft brush.

FAQ

How are the pointed ends of the marquise protected?
The marquise is held in a Six-Prong setting with support at both pointed ends. Those end prongs protect the most exposed parts of the 11.96 mm outline.

How many side diamonds does this ring have?
There are 2 round accent diamonds totaling approximately 0.05 ct. The remaining floral and leaf detail is sculpted metalwork rather than additional stones.

Why is the center raised above the shoulders?
The setting rises approximately 6.5–7.0 mm, keeping the elongated marquise clear of the floral metalwork. The open gallery also leaves the underside accessible for cleaning.

Will a straight wedding band sit completely flush?
The sculpted floral shoulders occupy space beside the raised center, so a straight band can leave a small gap. A contoured band follows the side profile more closely.

Which metal makes the leaf detail easiest to see?
Yellow and rose gold create stronger contrast through the carved leaves and vine openings. White gold and platinum make the setting read more continuously with the diamonds.
