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.

Spotlight

The marquise shape is celebrated for its elegant proportions and elongated appearance. Surrounded by a sparkling halo, the center diamond appears larger while maintaining a refined, sophisticated look that's perfect for those who appreciate understated luxury.

About Lab Grown Diamonds

The marquise brilliant cut combines exceptional sparkle with an elongated outline that naturally enhances finger length. Its pointed ends and curved sides create a distinctive silhouette that has remained a favorite for generations.

Every Signora lab grown diamond is chemically, physically and optically identical to a mined diamond and graded using the same international standards. Choosing lab grown means enjoying outstanding beauty, exceptional value, a documented origin and a responsible alternative without mining.

Metal, Care & Fit

Available in Sterling Silver, 9K, 14K and 18K yellow, white and rose gold, plus Platinum. Choose your regular ring size for the best fit, and most precious metal versions can be professionally resized if needed. Clean regularly with warm water, mild soap and a soft brush before drying with a lint-free cloth. Store separately to preserve the high-polish finish.
