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 cushion lab grown diamond solitaire engagement ring from Signora Jewels.

Shown with a 7.30 × 7.30 mm cushion-cut lab grown diamond weighing approximately 2.43 ct, secured in a classic four-prong setting. IGI-certified center diamond.

Made to order — the price updates with your selection. Want something fully custom? Customize your jewelry here.

The cushion cut blends soft rounded corners with brilliant faceting, giving the diamond broad flashes of light and a full face-up appearance. The four-prong setting keeps the outline open so light reaches the stone from every direction.

The woven shoulders give this solitaire its character. Instead of a plain band, the metal wraps and crosses beneath the center, creating texture that catches the eye before flowing into a comfortable rounded shank.

Select your preferred center diamond size from 1 to 4.5 carats and your favorite metal. Every ring is made to order by Signora Jewels, keeping the proportions balanced for the diamond you choose.

About Lab Grown Diamonds

A cushion cut combines rounded corners with brilliant facets, producing large flashes of light while maintaining a soft outline that has remained one of the most popular engagement ring shapes.

Every Signora Jewels lab grown diamond is chemically, physically and optically identical to a mined diamond and graded using the same 4Cs. You receive a documented origin, exceptional value and a diamond created without mining.

Metal, Care & Fit

Available in sterling silver, 9K, 14K and 18K yellow, white and rose gold, plus platinum. Order your regular ring size. Gold and platinum versions can usually be resized later if required. Clean with warm water, mild soap and a soft brush before drying with a lint-free cloth.

Are lab grown diamonds real diamonds?
