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 brilliance with clean, modern lines. At the center sits a striking radiant-cut diamond framed by a delicate halo that amplifies its size and sparkle from every angle.

The rectangular silhouette gives the ring a confident presence on the hand, while the halo of round lab grown diamonds softens the edges with a continuous frame of light. An open gallery beneath the center allows light to enter freely, enhancing fire and brilliance throughout the stone.

Made to order in your chosen center size and metal, this design balances everyday comfort with statement-making sparkle, creating a ring that feels personal from the moment it is crafted.

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, 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.

Does the halo come with the ring?
Yes. The halo design and accent diamonds are included as shown and are built into the setting.

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

Will a radiant cut sparkle as much as a round diamond?
A radiant cut uses brilliant faceting that delivers exceptional sparkle while offering a larger rectangular appearance than many other shapes.

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