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 solitaire engagement ring from Signora Jewels.

An approximately 1.00 ct emerald cut diamond measuring 6.66 × 4.70 × 3.17 mm is secured in a classic four-prong open basket, allowing light to enter from every side while highlighting the clean step-cut facets.

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 emerald cut is all about precision. Long step facets create broad flashes of light instead of scattered sparkle, giving the diamond a calm, mirror-like appearance. At Signora Jewels, this solitaire keeps every distraction away from the center with a slim comfort-fit shank and an open basket that leaves the side profile clean.

The approximately 1.70 mm band feels light on the finger while naturally drawing the eye toward the rectangular center stone. The cathedral-free profile keeps the design balanced, and the approximately 5.90 mm setting height provides enough clearance beneath the diamond for easy cleaning without making the ring feel unnecessarily tall.

FAQ

Why does an emerald cut sparkle differently?
The emerald cut uses long step facets rather than brilliant facets. Instead of many small flashes, it produces larger reflections that move across the diamond as it turns.

Does the open basket make cleaning easier?
Yes. The open gallery allows access beneath the diamond with a soft brush, making routine cleaning much simpler than in a closed setting.

Can this solitaire ring be stacked with a wedding band?
Yes. The straight comfort-fit shank pairs well with classic wedding bands, allowing a clean and balanced bridal set.

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