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 radiant lab grown diamond halo engagement ring is designed for someone who loves bold finger coverage and brilliant sparkle. At its center sits a radiant-cut diamond framed by a delicate halo that amplifies its presence without overwhelming the clean geometry of the stone.

The rectangular radiant shape combines crisp lines with lively brilliance, while the surrounding round diamonds create a continuous border of light. From across the room, the halo enhances the center stone's visual size; up close, the contrast between shapes adds depth and detail.

Finished with a sleek high-polish band and elegant cathedral shoulders, this made-to-order design offers the flexibility to choose both your preferred center size and metal, creating a ring that feels uniquely yours.

About Lab Grown Diamonds

A radiant marries an emerald's trimmed-corner outline with brilliant faceting, so it throws lively sparkle while keeping a bold rectangular footprint. The cropped corners are structurally tough and seat securely in prong or halo settings.

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 identical to mined diamonds in chemistry, hardness, and sparkle, and are graded on the same 4C scale.

What does the halo add?
The halo surrounds the center diamond with 26 accent diamonds, increasing overall sparkle and creating a larger visual appearance.

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 ring is crafted specifically to your selected center size and metal choice.
