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

A marquise stretches weight across a long, pointed boat shape, so it presents one of the largest face-up sizes per carat. Its tapering ends draw the eye down the finger and make a confident, regal statement.

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.

FAQ

What makes the split shank design special?
The split shank creates extra visual width and elegance, helping frame the halo while adding additional diamond sparkle along both sides of the band.

Does the halo make the center diamond look larger?
Yes. The halo surrounds the marquise center with additional diamonds, creating a larger visual footprint and enhancing overall brilliance.

Can this ring be customized?
Choose your options on this page; for anything beyond that we make custom pieces — Customize your jewelry here.

Does the price include the center diamond?
Yes. The listed configuration includes the center lab grown diamond.

Are lab grown diamonds real diamonds?
Yes. They are identical to mined diamonds in chemistry, hardness, and sparkle, and are graded on the same 4C scale — the only difference is origin.

What metals and colors can I choose?
Silver, 10K, 14K, and 18K Gold, and Platinum — gold is available in yellow, white, and rose.

How do I get the right ring size, and can it be resized?
Choose your size at checkout; most designs can also be resized. Contact us for guidance on this specific style.

Is the stated diamond measurement exact?
Measurements are approximate and can vary slightly with each diamond's proportions and cut.
