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.

About Lab Grown Diamonds

Emerald-cut diamonds are admired for their sophisticated step-cut facets and elegant hall-of-mirrors effect. Unlike brilliant cuts that emphasize sparkle, the emerald cut showcases exceptional clarity and refined flashes of light. The surrounding round brilliant diamonds provide additional fire and brilliance, creating a beautiful contrast.

Every Signora diamond is lab grown—chemically, physically and optically identical to a mined diamond while offering exceptional beauty, a documented origin. They deliver the same lasting durability and brilliance while supporting a more responsible approach to fine jewelry.

Metal, Care & Fit

Choose from Sterling Silver, 9K, 14K or 18K Yellow, White or Rose Gold, or Platinum. Every ring is handcrafted to order and finished with a brilliant high polish. Order your usual ring size for the best fit. To maintain its beauty, clean occasionally with warm water, mild soap and a soft brush, then store separately when not in use.
