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.

An emerald cut lab grown diamond sits between two trillion side stones, creating a clean three-stone profile with long, uninterrupted lines. Signora Jewels makes every ring to order, allowing each piece to be crafted in your selected precious metal.

The 7.00 × 5.00 mm center diamond is raised in an open prong setting so light reaches the step facets from every direction. The trillion side diamonds taper naturally into the shoulders, giving the ring a wider appearance across the finger while keeping the band refined and comfortable for daily wear.

The long step facets of the emerald cut contrast beautifully with the pointed trillion side stones, creating broad flashes of light and a balanced, architectural look from every angle.

About Lab Grown Diamonds

Emerald cut diamonds are known for their long step facets and mirror-like reflections. Their clean geometry highlights clarity while producing broad flashes of light instead of intense sparkle.

Every lab grown diamond from Signora Jewels is chemically, physically and optically identical to a mined diamond. Each is graded to the same 4C standards and offers a documented origin 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. Clean with warm water, mild soap and a soft brush, then dry with a soft lint-free cloth. Store separately to maintain its high-polish finish.
