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 green Dutch marquise cut lab grown diamond solitaire engagement ring from Signora Jewels.

One elongated 13.0 × 6.5 mm green diamond weighing approximately 2.00 ct, with no additional stones.

Six protective prongs, including pointed-end supports, hold the center above a raised open gallery.

A plain polished 2.00 mm lower shank with 10K, 14K and 18K yellow, white or rose gold, silver and platinum choices.

The two sharply pointed ends make this green marquise especially distinctive. Signora Jewels sets the 13.0 × 6.5 mm diamond lengthwise, with shaped metal prongs covering each point and four side claws securing the wider edges. The green facets remain visible across the face, without a metal bezel or diamond halo.

The band is deliberately plain. There are no shoulder diamonds, pavé rows or decorative borders to interrupt the rich green center. The polished shoulders measure approximately 2.00–2.20 mm, continuing into a 2.00 mm lower shank. Beneath the center, an open gallery leaves space for light to enter around the diamond.

Metal, Care & Fit

Choose 10K, 14K or 18K yellow, white or rose gold, silver or platinum. The polished band is smooth, but the raised prongs can catch on delicate knitwear. Clean with warm water, mild soap and a soft brush, gently working around the six prongs and beneath the open basket. Remove the ring before heavy lifting or direct impact.

FAQ

Is the green center a lab grown diamond? Yes. The center is a green Dutch marquise cut lab grown diamond weighing 2.00 ct in this fixed design.

How are the pointed ends protected? Protective metal prongs cover both narrow tips, while four side claws secure the diamond along its broader edges.

Does this ring have any side diamonds? No. The ring contains one 2.00 ct center diamond only, with plain polished shoulders and no halo.

How wide is the band? The lower shank is approximately 2.00 mm wide, while the shoulders measure about 2.00–2.20 mm.

How should I care for the raised setting? Clean gently around the six prongs and underneath the center basket using mild soap and a soft brush. Avoid hard knocks against the marquise tips.
