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.

The photographed design centers a 1.70 ct Dutch marquise measuring approximately 11.2 × 6.0 mm in a six-prong setting, with 14 marquise and round accent diamonds totaling approximately 0.20 ct. Approx. 1.90 ct total.

Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.

Each metal color is shown in the photos. 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 sets the 11.2 × 6.0 mm Dutch marquise inside a band that branches around the center instead of meeting it in a straight shoulder. Six prongs secure the photographed 1.70 ct diamond, with dedicated contact at both pointed ends, while polished vines curl through the open spaces on either side.

Four small marquise diamonds follow the leaf shapes and ten rounds fill the tighter turns in the vine, adding approximately 0.20 ct altogether. The botanical shoulders reach about 5.00 mm near the center before narrowing to a 2.20 mm lower shank.

Design highlights

Dutch marquise center customizable from 1 to 4.5 ct
1.70 ct reference center measuring approximately 11.2 × 6.0 mm
Four marquise accent diamonds totaling approximately 0.12 ct
Ten round accent diamonds totaling approximately 0.08 ct
Six-prong center setting with protection at both pointed ends
Open leaf-and-vine shoulders reaching approximately 5.00 mm near the center

The accent shapes follow the metal instead of sitting in a conventional row. Marquise cuts become pointed leaves, rounds occupy the smaller bends, and open sections between the vines let the branching pattern remain visible.

About Lab Grown Diamonds

The Dutch marquise reference center measures approximately 11.2 × 6.0 mm at 1.70 ct. Its elongated outline ends in two narrow points, so the six-prong arrangement protects both tips while additional contact points support the long sides. Marquise and round accents repeat that mix of pointed and curved forms through the shoulders.

Metal, Care & Fit

The reference construction uses approximately 6.30 g of 18K gold before the diamonds are set. Yellow and rose gold make the branching vines easier to distinguish; white gold and platinum keep the accent settings closer in tone to the stones. Clean from both sides with warm water, mild soap and a soft brush, working between the open vines and behind the smaller diamonds.

FAQ

How are the pointed ends of the Dutch marquise protected?
The six-prong setting includes contact at both pointed ends of the center. Those end prongs protect the most vulnerable areas of the approximately 11.2 × 6.0 mm reference diamond.

What do the mixed-shape accents add to the vine shoulders?
Four marquise and ten round diamonds add approximately 0.20 ct in the photographed design. The marquise cuts follow the pointed leaf forms while rounds fit the tighter curves in the vine.

How wide are the nature-inspired shoulders?
The branching shoulder area reaches approximately 5.00 mm near the center before narrowing into a 2.20 mm lower shank. Open spaces between the vines break up that width.

How high does the 1.70 ct reference setting sit?
The photographed setting is approximately 7.50 mm high. Its open gallery leaves access beneath the center while the vines approach the basket from either side.

How should I clean between the leaves and accent diamonds?
Use warm water, mild soap and a soft brush from both sides. Brush behind the four marquise and ten round accents as well as through the open vine sections where residue can collect.
