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 marquise center is held in six prongs, with petite round diamonds tucked beneath the basket for a soft flash from the side.

Crafted as modeled, this ring keeps the diamond, design, and ring size fixed; you simply choose the metal that feels most like you.

About Lab Grown Diamonds

A pear is a teardrop hybrid of round and marquise: brilliant sparkle at the belly tapering to a single point that lengthens the finger. The tip should sit in a protective V-prong, and the silhouette gives a distinctive, directional look.

Every Signora Jewels diamond is grown in a controlled lab using the CVD process, producing a stone that is chemically, optically, and physically identical to a mined diamond — same hardness, same fire, graded on the same 4C scale. Because the supply chain is short and traceable, you get a larger, cleaner stone for the same budget and a documented origin, with no mining footprint. The result is a diamond that looks and tests exactly as a natural one, with more carat and clarity for your money.
