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.

This round lab grown diamond engagement ring is designed to bring sparkle from every angle. A brilliant round center rises above a hidden halo while the split shank sweeps outward, creating an open, airy profile that draws attention straight to the diamond.

The pavé-set diamonds along both arms of the split band add extra light without overwhelming the center stone. From the top, the design feels balanced and elegant; from the side, the hidden halo reveals an unexpected ring of brilliance beneath the center.

Made to order in your choice of center size and metal, this ring combines the timeless appeal of a round diamond with a modern split shank silhouette crafted for everyday comfort and lasting beauty.

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

Can I change the center stone size?
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. They are chemically, physically, and optically identical to mined diamonds and are graded using the same 4C standards.

What does the hidden halo add?
The hidden halo adds an extra circle of sparkle beneath the center diamond, creating brilliance from side angles while maintaining a clean top view.

Which metals can I choose?
Silver, 9K / 14K / 18K gold in yellow, white or rose, and Platinum.

Is this ring made to order?
Yes. Every Signora Jewels ring is crafted to order according to the center size and metal option you select.
