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 round lab grown diamond solitaire engagement ring from Signora Jewels.

The ring shown features a round brilliant lab grown diamond measuring approximately 5.90–6.00 mm and weighing approximately 1.00 ct. The elegant split shank and cathedral basket create a contemporary solitaire profile that keeps the center diamond as the focal point.

Made to order in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum.

Available with customizable center diamond sizes from 1 ct to 4.5 ct.

The four-prong cathedral basket raises the round brilliant diamond above the band, allowing light to enter through the open gallery beneath. This design maximizes brilliance while securely holding the center stone and maintaining an elegant side profile.

The split shank gradually opens as it approaches the center before flowing back into a polished comfort band. Without additional accent diamonds, the design remains clean, contemporary and entirely focused on the brilliance of the solitaire. Signora Jewels handcrafts every ring to order in your selected precious metal.
