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 cluster engagement ring from Signora Jewels.

A 1.00 ct, 10.00 × 4.85 mm Dutch marquise center is framed by cyan-blue and white round diamonds totaling approx. 0.14 ct. Approx. 1.14 ct total.

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

Signora Jewels sets the 10.00 × 4.85 mm Dutch marquise between compact cyan-blue and white round clusters, giving this engagement ring color at the shoulders without surrounding the center in a halo. The pointed Dutch marquise stays visually long and narrow while the round stones broaden the setting near its midpoint.

The setting sits approximately 5.8–6.3 mm high. At the base, the shank measures about 1.70 mm wide and 1.80 mm thick, keeping the lower band slim beneath the colored cluster work.

Design highlights

1.00 ct Dutch marquise center, approx. 10.00 × 4.85 mm
Cyan-blue and white round accent diamonds totaling approx. 0.14 ct
Prong-set elongated center diamond
Symmetrical Cluster shoulders on both sides
Color concentrated beside the center rather than around its face
Approx. 1.14 ct total diamond weight

The cyan-blue rounds sit closest to the center among the white accents, so the color reads as part of the shoulder structure rather than a separate gemstone element. The polished shank then narrows away from the clusters without another row of diamonds.

About Lab Grown Diamonds

The Dutch marquise gives the center a pointed, elongated outline with more geometric shoulders than a standard marquise. The smaller rounds add a tighter sparkle pattern beside it. Read more in the diamond stone guide.

Metal, Care & Fit

White gold and platinum make the cyan-blue accents stand apart sharply from the white diamonds, while yellow and rose gold add warmer contrast around the cluster setting. Compare choices in the metal guide. Clean around the small shoulder stones and beneath the center with warm water, mild soap and a soft brush.

FAQ

Are the cyan-blue shoulder stones also lab grown diamonds?
Yes. The cyan-blue and white round accents in this design are lab grown diamonds, with approximately 0.14 ct combined accent weight.

How much diamond weight is beside the Dutch marquise?
The cyan-blue and white round accents total approximately 0.14 ct. Together with the 1.00 ct center, the ring carries approximately 1.14 ct total diamond weight.

How does the Dutch marquise wear on the finger?
The 10.00 × 4.85 mm center creates a long north-to-south line. Its narrow width keeps the center elongated even with the round clusters adding width at the shoulders.

Which metal gives the cyan-blue accents the strongest contrast?
White gold and platinum create the clearest visual separation between the cyan-blue and white diamonds. Yellow and rose gold give the entire cluster a warmer frame.

How should the round cluster accents be cleaned?
Use a soft brush around the small round settings and beneath the center. The spaces between the clustered stones collect more residue than the plain polished lower shank.
