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 Dutch marquise lab grown diamond side stone engagement ring from Signora Jewels.

A 1.50 ct, 11.44 × 5.47 mm Dutch marquise center sits above a round accent diamond totaling approx. 0.03 ct. Approx. 1.53 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 11.44 × 5.47 mm Dutch marquise inside an asymmetrical botanical setting, with a sculpted rose on one shoulder and carved leaves climbing around the center. A small round diamond sits within the opposite side detail, adding one bright point without turning the ring into a pavé design.

The center rises approximately 6.5–7.0 mm above an open floral gallery. The lower band stays about 2.00 mm wide and 1.70 mm thick, while the shoulder work spreads to roughly 6.0–7.5 mm around the dimensional rose and vine forms.

Design highlights

1.50 ct Dutch marquise center in the reference design
Center measures approx. 11.44 × 5.47 mm
Round accent diamond totaling approx. 0.03 ct
Six-Prong elevated center setting
Three-dimensional rose with sculpted leaf-and-vine shoulders
Open botanical gallery beneath the center

The asymmetry is the defining detail. One side carries the dimensional rose while the opposite shoulder climbs in leaves and vines, so the center does not sit inside a conventional mirrored frame. See more engagement rings with sculptural settings.

About Lab Grown Diamonds

The Dutch marquise gives the center a long pointed profile with more geometric shoulders than a standard marquise. At 11.44 mm long in the reference design, it carries most of its visual spread along the finger. Read more in the diamond stone guide.

Metal, Care & Fit

Yellow and rose gold make the sculpted rose and leaf relief easier to read, while white gold and platinum keep more attention on the diamonds. Compare choices in the metal guide. Clean between the rose petals, beneath the open gallery and around the small accent with warm water, mild soap and a soft brush.

FAQ

What makes this Dutch marquise ring asymmetrical?
The shoulders are deliberately different on each side. One carries a three-dimensional rose, while the opposite side uses climbing leaf-and-vine metalwork around the round accent.

How much accent diamond weight is in the botanical setting?
The round side accent totals approximately 0.03 ct. The rest of the floral detail is sculpted metal rather than additional diamonds.

How are the pointed ends of the Dutch marquise protected?
The center uses a Six-Prong setting with support at both pointed ends and along the sides. The prongs keep the 11.44 × 5.47 mm reference outline secure while leaving it clearly visible.

How high does the center sit?
The reference setting rises approximately 6.5–7.0 mm. That elevation leaves an open floral gallery underneath the Dutch marquise.

How should the sculpted rose be cleaned?
Use a soft brush between the raised petals and leaf recesses, then work underneath the center gallery. Those sculpted areas hold more residue than the polished lower band.
