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 round lab grown diamond crossover engagement ring from Signora Jewels.

A 0.50 ct round brilliant, approx. 5.1–5.2 mm, sits in a Four-Prong center inside a pavé halo; crossover shoulders carry another approx. 40–42 round diamonds. Approx. 0.88 ct total.

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

Made to order in your chosen metal with a fixed, approximately 0.50 ct round center.

Signora Jewels sets the 5.1–5.2 mm round center inside a pavé halo, then splits the shoulders into two diamond-set paths that cross before returning to the band. The result is wider beside the center without turning into one solid pavé strip.

Approximately 20–22 rounds circle the center, while another 40–42 continue through the crossover shoulders. The lower shank narrows to about 1.65 mm.

Design highlights

Four-Prong center framed by a pavé halo
Approx. 20–22 halo diamonds totaling approx. 0.13 ct

Approx. 0.88 ct total across approx. 61–65 diamonds

The crossing shoulders are what separate this ring from a straight halo engagement ring. One pavé line rises while the other passes beneath it, opening small gaps between the two paths before they rejoin the lower band.

About Lab Grown Diamonds

The round brilliant center and small round accents repeat the same circular facet pattern at three scales: center, halo and shoulders. Our diamond stone guide explains how round cuts return light.

Metal, Care & Fit

The crossover section contains more small prongs and openings than a plain band. Use a soft brush around both pavé paths and behind the halo, following our jewelry care guide.

FAQ

How wide is the crossover section beside the 0.50 ct center?
The split pavé shoulders span approximately 3.5–4.2 mm near the center before narrowing into a 1.65 mm lower shank. That extra width comes from two crossing diamond-set paths rather than one broad solid band.

How many diamonds sit outside the round center?
Approximately 60–64 accent diamonds surround and flank the center. About 20–22 form the halo and another 40–42 run through the crossover shoulders, totaling approximately 0.38 ct.

Are both crossing shoulder paths set with diamonds?
Yes. Both arms of the crossover carry small round pavé diamonds, so the diamond line continues through the twist instead of leaving one arm plain.

How should I clean where the two pavé shoulders cross?
Use warm water, mild soap and a soft brush through the gaps between the two crossing arms. Work lightly around the small prongs, rinse thoroughly and pat dry rather than pulling cloth through the crossover openings.

Will a straight wedding band sit flush beside this crossover halo?
The crossover shoulders reach approximately 3.5–4.2 mm across near the center and the setting is approximately 6.0–6.5 mm high. Those measurements do not guarantee side clearance, so compare the finished ring with the intended band before assuming a flush fit.
