The round brilliant center is secured by a four-prong basket that rises from a cathedral gallery, allowing light to reach the pavilion while keeping the diamond elevated above the shoulders. A close-fitting halo surrounds the center to emphasize its circular outline and increase its visual spread without changing the classic proportions.
The infinity shank twists beneath the halo before flowing into a polished comfort band. Thirty-two round brilliant diamonds follow the twisting shoulders, creating continuous sparkle that naturally draws attention toward the center stone. Signora Jewels crafts every ring to order in your selected precious metal and center diamond size.

FAQ
What does the infinity shank add to the design?
The twisting shoulders create a flowing profile that naturally leads the eye toward the center while providing additional pavé sparkle.
Can I choose a different center diamond size?
Yes. This design is available with center diamond options from 1 ct through 4.5 ct while maintaining the same halo and infinity shank style.
Does the halo make the center diamond appear larger?
Yes. The eighteen surrounding round diamonds frame the center stone, increasing its visual presence while preserving its round outline.
Is the cathedral setting suitable for everyday wear?
Yes. The cathedral shoulders reinforce the basket, and the polished lower shank provides a comfortable fit for daily wear.
