Signora Jewels sets the 1.00 ct cushion inside a close halo that follows its softly squared outline. Four rounded prongs hold the 5.80 × 5.80 mm center at its corners, while the open basket leaves clear access beneath the diamond for cleaning.
Twenty round diamonds form the halo. Another thirty run along the cathedral shoulders, carrying the pavé line upward until it meets the center setting. The raised shoulders support the basket from both sides without closing the gallery with extra metal.

About Lab Grown Diamonds
A cushion cut pairs rounded corners with a square face and broad reflections through the center. Here, the round halo follows those curved corners closely, adding width without changing the center diamond’s balanced proportions.
Metal, Care & Fit
White Gold and Platinum keep the halo visually connected to the center. Yellow or Rose Gold outlines the white diamonds more clearly. Clean between the halo stones, beneath the open basket and along both pavé shoulders with warm water, mild soap and a soft brush. A curved band gives the closest fit beneath the raised setting.
FAQ
How are the cushion diamond’s corners protected?
Four rounded prongs sit over the corners of the 5.80 × 5.80 mm center, securing the stone without covering its softly squared outline.
What does the halo add to this cushion design?
Twenty round diamonds add approx. 0.16 ct and create a bright border that makes the 1.00 ct center read wider from above.
Will a straight wedding band sit flush beside this ring?
The raised halo and cathedral shoulders create a contour near the center, so a curved wedding band gives the closest fit.
How should the cathedral pavé shank be cleaned?
Brush gently along both shoulders and beneath the open basket, where lotion and soap collect around the 30 band diamonds.
