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.

At a glance

A Dutch marquise lab grown diamond nature-inspired engagement ring from Signora Jewels.

Main diamond: approx. 1.70 ct · Side diamonds: approx. 0.11 ct · Total diamond weight: approx. 1.81 ct.

The CAD uses 7 diamonds: one Dutch marquise center, two marquise side diamonds and four round side diamonds.

The reference design measures approximately 12.7 mm across the center area, with a 6.35 mm setting height, 2.00 mm upper profile and 1.60 mm lower shank.

Choose a 1 ct, 1.5 ct, 1.7 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct center and your preferred metal from the options on this page.

Signora Jewels builds the shoulders around the long 11.66 × 5.71 mm Dutch marquise instead of running a conventional pavé row beside it. Six prongs secure the photographed center, including protection at both pointed ends, while polished vines cross through raised leaves on either side.

Two 3.0 × 1.5 mm marquise diamonds sit like leaves close to the center. Four 1.50 mm rounds add smaller flashes farther through the vine work. Together the six side diamonds weigh approximately 0.11 ct, bringing the 1.70 ct reference center to approximately 1.81 ct total diamond weight.

Design highlights

1.70 ct Dutch marquise center measuring 11.66 × 5.71 × 4.30 mm
Two 3.0 × 1.5 mm marquise side diamonds totaling approx. 0.05 ct
Four 1.50 mm round side diamonds totaling approx. 0.06 ct
0.11 ct total side diamond weight and approx. 1.81 ct total diamond weight
Six-prong center setting with protection at both pointed ends
Open sculptural leaf-and-vine shoulders with individually placed accents

The diamonds follow the botanical structure rather than covering it. The marquise accents repeat the pointed leaf shapes closest to the center, while the smaller rounds sit inside the narrower turns of the vines.

About Lab Grown Diamonds

The reference Dutch marquise weighs approximately 1.70 ct. Six smaller diamonds add approximately 0.11 ct: two marquise accents total 0.05 ct and four rounds total 0.06 ct. The complete reference design therefore carries approximately 1.81 ct across seven diamonds.

Metal, Care & Fit

The CAD gives an 18K metal weight of 4.40 g. The open vine structure leaves access behind the smaller stones and beneath the center. Use warm water, mild soap and a soft brush through the openings, paying particular attention to the two pointed ends of the center and the recessed areas around the leaves.

FAQ

What is the total diamond weight of this Dutch marquise ring?
The reference design carries approximately 1.81 ct total. That combines the approximately 1.70 ct main diamond with approximately 0.11 ct of side diamonds.

What diamonds are set through the vine shoulders?
Six side diamonds total approximately 0.11 ct. Two are 3.0 × 1.5 mm marquise cuts totaling approximately 0.05 ct, and four are 1.50 mm rounds totaling approximately 0.06 ct.

How is the Dutch marquise center protected?
Six prongs secure the elongated center, including metal at both pointed ends. The remaining contact points support the long sides while leaving much of the 11.66 × 5.71 mm outline visible.

How high does the reference setting sit?
The CAD shows approximately 6.35 mm through the center setting. Open vine and leaf work rises toward the diamond instead of forming solid shoulders beneath it.

How should the leaf-and-vine details be cleaned?
Use warm water, mild soap and a soft brush from both sides. Work behind the six smaller diamonds and through the open vine sections, where residue can settle around the sculpted leaves.
