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 round lab grown diamond split shank engagement ring from Signora Jewels.

A 0.73 ct round brilliant, 5.72 × 5.72 × 3.58 mm, sits inside a pavé halo of approx. 18–20 rounds; another approx. 24–28 rounds run along the diamond-set split arm. Approx. 1.07 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 the fixed 0.73 ct round center.

Signora Jewels splits the shoulders of this engagement ring into two different paths. One carries pavé diamonds; the other stays polished metal, and the two twist past one another before meeting the halo.

The center measures 5.72 mm across and is held by four rounded prongs. Around it, approximately 18–20 small rounds form the halo, while another 24–28 continue through the diamond-set arm.

The contrast between the two arms is the point of the design. One catches light through a line of small rounds while the other reflects as uninterrupted metal, so the twist stays visible instead of disappearing into an all-pavé band.

About Lab Grown Diamonds

The round brilliant center and the smaller round accents repeat the same circular outline at different scales. Our diamond stone guide explains how round cuts handle light.

Metal, Care & Fit

The pavé arm needs more brushing than the polished arm because residue can collect between its small prongs. Use mild soap, warm water and a soft brush, following our jewelry care guide.

FAQ

Are both arms of this split shank diamond-set?
No. One arm carries pavé round diamonds while the opposing arm is primarily polished metal. That contrast keeps the twisted split visible from the front.

How many diamonds sit outside the 0.73 ct center?
Approximately 42–48 accent diamonds sit outside the center, totaling about 0.34 ct. Roughly 18–20 form the halo and another 24–28 sit along the pavé arm.

How wide is the twisted section near the halo?
The split section spans approximately 3.8–4.5 mm near the center before narrowing to an approximately 2.00 mm lower shank. The added width comes from the two separate arms rather than a solid band.

How should I clean where the two arms cross?
Use a soft brush through the openings between the split arms and around the pavé prongs. Rinse thoroughly and pat dry rather than pulling cloth through the crossover spaces.

Will a straight wedding band sit flush beside this split shank?
The setting height is approximately 6.2–6.8 mm and the shoulders widen through the twisted section. Those measurements do not guarantee side clearance, so compare the finished ring with the intended band before assuming a flush fit.
