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

An emerald cut lab grown diamond split shank engagement ring from Signora Jewels.

An approximately 1.50 ct emerald cut diamond measuring 8.11 × 5.46 × 3.46 mm is secured by four double-claw prongs in an open cathedral basket with a split shank.

Made to order in 11 metals: Silver, 9K/14K/18K Gold (Yellow, White and Rose) and Platinum.

Each metal color is shown in the photos. Choose your preferred center diamond weight and metal from the options on this page.

The split shank opens beneath the emerald cut before flowing into a cathedral basket that lifts the center without adding unnecessary bulk. At Signora Jewels, four double-claw prongs secure each corner while leaving the long step facets completely visible, allowing the clean geometry of the emerald cut to remain the focus.

The approximately 1.85 mm comfort-fit shank feels light on the hand, while the 6.60 mm setting height creates an airy side profile and allows light to reach the pavilion through the open gallery. The split shoulders frame the center from below rather than distracting from it.

The open split beneath the basket gives the ring a lighter appearance from the side while naturally directing attention toward the emerald cut. The double-claw prongs add crisp definition to each corner without interrupting the clean outline of the center stone.

About Lab Grown Diamonds

The emerald cut is recognized for its long step facets and broad mirror-like reflections. Every center diamond is F color, VS1 clarity and , selected to complement the clean proportions of this split shank cathedral design.

Metal, Care & Fit

FAQ

Why does this ring use a split shank?
The split shoulders create open space beneath the center diamond while supporting the cathedral basket. This gives the ring a lighter appearance without reducing stability.

What is the benefit of double-claw prongs?
Each corner is secured by two fine claw tips instead of one. This provides additional corner protection while keeping the outline of the emerald cut crisp.

Can this ring be worn with a wedding band?
Yes. The cathedral basket allows many straight wedding bands to sit close, while contoured bands can follow the raised profile even more precisely.

Which metal color best suits an emerald cut?
White gold and platinum emphasize the clean step-cut geometry, while yellow and rose gold provide warm contrast around the center diamond.
