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 halo engagement ring from Signora Jewels.

An approximately 1.50 ct Dutch Marquise center measuring 11.71 × 5.73 mm sits in a six-prong open gallery, framed by 26 round diamonds totaling approximately 0.14 ct.

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 your preferred center diamond size and metal from the options on this page.

The long Dutch Marquise center gives this Signora Jewels engagement ring a striking finger-lengthening shape, while the halo follows every point of the outline instead of looking round from a distance. Six prongs secure the center and leave the sides open so light reaches the diamond from more than one direction.

The comfort-fit shank measures about 1.75 mm wide at the base, keeping the ring light on the hand while giving the center stone visual presence. The open gallery also makes routine cleaning underneath the center much easier.

The halo closely follows the Dutch Marquise outline instead of creating extra width around it. From across the room the eye reads one larger diamond, while up close the fine round accents create crisp sparkle around every point.

About Lab Grown Diamonds

The elongated Dutch Marquise cut combines bright reflections through the center with pointed ends that emphasize its distinctive outline. Every diamond is F color, VS1 clarity and , then matched to the selected setting size for balanced proportions.

Metal, Care & Fit

Available in silver, 9K, 14K and 18K yellow, white or rose gold, plus platinum. Clean the ring with warm water, mild soap and a soft brush, paying extra attention beneath the open gallery where everyday residue naturally gathers.

FAQ

Will the pointed ends catch during daily wear?
The six-prong head protects the pointed ends while keeping the outline open. Normal daily wear is comfortable, although removing the ring for heavy manual work is always recommended.

Why does the halo make the center look larger?
Twenty-six small round diamonds trace the full Dutch Marquise outline instead of competing with it. Your eye reads a larger overall silhouette while the center remains the focus.

Can I wear a wedding band beside this ring?
The open gallery allows many straight bands to sit close, although a contoured band follows the halo outline most closely.

Which metal color suits this design best?
White gold emphasizes the crisp outline of the halo, yellow gold creates stronger contrast around the center, and rose gold gives the design a warmer appearance without changing the diamond color.
