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.

The clean step facets of the emerald cut meet the sharp angles of trillion side diamonds, creating a three-stone ring that looks balanced from every direction. The center sits proudly above the band while the side stones taper naturally into the shoulders, drawing the eye across the full width of the design instead of only the center.

With approximately 2.00 carats of lab grown diamonds, this ring brings broad flashes of light rather than glitter. The open prong setting lets light enter from every side, while the slim high-polish band keeps the focus where it belongs—on the diamonds.

The contrast between the long step facets of the emerald cut and the pointed trillion side stones gives this ring its character. From the top it feels crisp and geometric, while the angled side diamonds widen the look across the finger.

About Lab Grown Diamonds

Emerald cut diamonds are known for broad flashes of light and exceptional clarity. Their long step facets create a clean, mirror-like appearance that highlights the precision of the cut.

Every Signora diamond is lab grown—chemically, physically and optically identical to a mined diamond and graded using the same 4C standards. They provide the same beauty while offering a fully traceable origin.

Metal, Care & Fit

Available in sterling silver, 9K, 14K and 18K yellow, white and rose gold, plus platinum. Order your regular ring size. Clean with warm water, mild soap and a soft brush, then dry with a lint-free cloth.
