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.

The four-prong basket holds the round brilliant center securely while the open gallery allows light beneath the diamond. The halo closely follows the outline of the center stone, increasing its face-up appearance while keeping the round shape clearly defined.

The infinity split shank twists gently beneath the halo before flowing into a polished comfort band. Thirty pavé-set diamonds continue across both shoulders, creating uninterrupted sparkle that leads naturally toward the center. Signora Jewels makes every ring to order in your selected precious metal and center diamond size.

About Lab Grown Diamonds

The round brilliant cut is designed for maximum light return, producing balanced sparkle from every angle. The surrounding halo increases the visual size of the center while the infinity pavé shank extends that brilliance across the ring.

Metal, Care & Fit

Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the open basket and along the pavé-set shoulders with warm water, mild soap and a soft brush to keep every accent diamond bright.

FAQ

What does the infinity split shank add to this design?
The split shank twists beneath the halo, creating a flowing profile that draws the eye toward the center diamond while adding extra pavé sparkle.

Can I choose a larger center diamond?
Yes. This design is available with center diamond options from 1 ct through 4.5 ct while maintaining the same halo and infinity shank design.

Does the halo make the center appear larger?
Yes. The eighteen surrounding round diamonds frame the center stone and increase its visual presence without changing its shape.

Is this ring comfortable for everyday wear?
Yes. The polished lower shank provides a smooth fit, while the cathedral basket keeps the center secure and supported during daily wear.
