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 cut lab grown diamond engagement ring with celestial and botanical goldwork from Signora Jewels.

A 13.0 × 6.5 mm marquise center weighing approx. 2.00 ct, with protective leaf prongs, four marquise accents totaling 0.10 ct and 8–12 round accents totaling 0.05 ct. Approx. 2.15 ct combined.

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

Choose your center diamond weight and metal from the options on this page.

The crescent moon sits to the left of the marquise, with a polished five-pointed star on the opposite shoulder. Signora Jewels sets a 13.0 × 6.5 mm Dutch marquise between leaf-shaped gold prongs that cover both pointed ends. Smaller marquise diamonds run outward through the vine-like branches, while round brilliants sit closer to the center and between the metal curves.

At the reference size, the center weighs 2.00 ct. Four marquise accents add 0.10 ct, with another 0.05 ct in approximately 8–12 round diamonds. Open spaces separate the crescent, star and leaf branches, letting each shape remain visible rather than merging into a solid shoulder.

About Lab Grown Diamonds

The Dutch marquise center has two pointed ends and an elongated arrangement of facets. The smaller marquise accents echo its pointed shape, while round brilliant diamonds add more concentrated flashes among the leaf and celestial metalwork. All diamonds are lab grown, with F color and VS1 clarity specifications. Read our diamond and stone guide for more about diamond shapes and proportions.

Metal, Care & Fit

Choose silver, 10K, 14K or 18K gold in yellow, white or rose, or platinum. The moon, star and branching goldwork have open spaces around small stone settings, so clean gently with warm water, mild soap and a soft brush. Pay particular attention to the leaf-shaped center prongs and the pointed side diamonds. Remove the ring before heavy lifting or when tight sleeves can catch on the raised setting.

FAQ

Are the moon and star made from diamonds?
No. The crescent moon and star are sculpted metalwork. The smaller diamonds are individually placed in the botanical branches and along the decorative shoulders.

Are both pointed ends of the Dutch marquise protected?
Yes. Leaf-shaped gold prongs cover the upper and lower points, while additional side prongs hold the center along its wider edges.

Do the side diamonds match the center shape?
Four smaller marquise diamonds echo the pointed center shape, while approximately 8–12 round brilliant accents fill selected spaces along the shoulders. The accents total 0.15 ct.

Can the center diamond weight be changed?
Yes. The Dutch marquise center is selectable from 1 ct to 4.5 ct, including the reference 2.00 ct. The center basket is made for the selected diamond dimensions.

How should I clean the open moon-and-vine details?
Use a soft brush with mild soap and warm water, gently working through the open spaces around the moon, star, leaf branches and small diamond settings. Rinse and pat dry without pulling on the metal details.
