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 engagement ring should feel bright from every angle, and this split shank design does exactly that. A 1.92 ct round center rises above two diamond-lined bands that draw the eye directly to the stone.

The open split shank creates a light, architectural profile while adding extra brilliance through thirty-two hand-set accent diamonds. From the front, the design feels balanced and elegant; from the side, the open structure gives the center diamond a floating appearance.

Made to order in your chosen metal and center size, this ring is crafted for the proposal moment and designed to be worn every day after it.

About Lab Grown Diamonds

A round brilliant is cut with 57–58 facets engineered to recycle light back to the eye, which is why it out-sparkles every other shape and hides small inclusions well. It is the most requested engagement silhouette and sits comfortably in solitaire, halo, or pavé settings without fighting the design.

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

Yes. Center sizes from 1 CT to 4.5 CT are available, and the setting is scaled to suit the stone you choose.

Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds and are graded on the same 4C scale.

Will a lab grown diamond last?
Yes. Lab grown diamonds are a 10 on the Mohs hardness scale and are suitable for everyday wear.

Can I choose a different metal?
Yes. This ring is available in Silver, 9K, 14K, and 18K yellow, white, and rose gold, as well as Platinum.
