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.

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

An approximately 1.00 ct emerald cut diamond measuring 6.60 × 4.70 × 3.14 mm is secured in a four-prong cathedral open basket.

Made to order in 11 metals: Silver, 10K/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 emerald cut is celebrated for its clean geometry and mirror-like step facets. At Signora Jewels, four refined prongs secure each corner while the cathedral basket gently elevates the center above the shank. The open gallery allows light to reach the pavilion, highlighting the crisp reflections that define this classic diamond shape.

The approximately 1.80 mm comfort-fit shank keeps the profile refined while naturally directing attention toward the center stone. With an approximate setting height of 5.80 mm, the ring offers a balanced silhouette that is comfortable for everyday wear while maintaining the elegance expected from a classic solitaire.

FAQ

Why is the emerald cut suited to a solitaire setting?
The clean step facets and rectangular outline are fully visible without surrounding accent stones, allowing the diamond's symmetry to become the main focus.

What is the benefit of a cathedral basket?
The cathedral shoulders support the basket while lifting the center diamond into stronger light. The open gallery also makes routine cleaning easier.

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

Which metal color best complements an emerald cut?
White gold and platinum emphasize the crisp step-cut geometry, while yellow and rose gold create warm contrast around the elegant rectangular center stone.
