Select your preferred center diamond size and precious metal using the options on this page.
The 9.20 × 7.10 mm radiant cut center sits in a four-prong cathedral basket that keeps the corners secure while leaving the pavilion open to light. The hidden halo sits beneath the center stone instead of around its outline, so from above the radiant remains the clear focal point while extra brilliance appears as the ring moves.
Four marquise accent diamonds are positioned along the shoulders, creating a graceful transition into the slim band without overpowering the center. The cathedral shoulders lift the basket above the finger while the open gallery keeps the profile light and makes cleaning beneath the center easier. Signora Jewels crafts every ring to order in your selected precious metal and diamond size.

About Lab Grown Diamonds
The radiant cut combines the crisp outline of an emerald shape with the sparkle of a brilliant facet arrangement. The hidden halo adds light beneath the center while preserving the clean outline of the radiant when viewed from above.
Metal, Care & Fit
Available in Silver, 9K, 14K and 18K Yellow, White and Rose Gold, plus Platinum. Clean beneath the hidden halo and around the marquise shoulder diamonds using warm water, mild soap and a soft brush to maintain maximum brilliance.
FAQ
What is the advantage of a hidden halo?
The hidden halo sits beneath the center stone, adding sparkle from side angles while keeping the top view focused on the radiant cut diamond.
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 overall style.
Why are marquise diamonds used on the shoulders?
Their elongated shape creates a graceful transition into the center basket without adding the visual weight of larger round accents.
Is the cathedral basket comfortable for everyday wear?
Yes. The cathedral shoulders support the basket from both sides while the slim band keeps the ring balanced for regular wear.
