Signora Jewels starts with a square 5.5 × 5.5 mm princess center, then builds the frame outward. Four prongs leave the straight sides and clipped corners easy to read, while 24 small rounds form the cushion-square halo around the photographed 1.00 ct diamond.
The frame is edged in fine milgrain, and another 14 rounds continue into the twisted shoulders. Those shoulders reach approximately 3.30 mm near the setting before settling into a 2.10 mm lower shank. At the reference weight, the head stands approximately 7.00 mm high.
Design highlights
- Princess center options: 1 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct
- 1.00 ct reference center measuring approximately 5.5 × 5.5 mm
- 24 round halo diamonds totaling approximately 0.17 ct
- 14 round shoulder diamonds totaling approximately 0.08 ct

The square center and shaped frame do different jobs. The princess keeps a crisp geometric center, while the rounded corners and pointed sections of the surrounding halo soften its outline and increase its face-up spread. The twist then carries the pavé into the band instead of ending it at the head. Browse more halo engagement rings, compare cuts in the diamond stone guide, or review the metal guide.

About Lab Grown Diamonds
The princess center concentrates its 1.00 ct reference weight into an approximately 5.5 × 5.5 mm square outline. Its straight sides contrast with the small round diamonds in the halo and shoulders, making the center shape easy to distinguish even inside a detailed frame.
Metal, Care & Fit
The reference construction uses approximately 5.87 g of 18K gold before the diamonds are set. Yellow and rose gold make the milgrain and twisted strands more visible between the rounds; white gold and platinum keep the halo closer in tone to the stones. Clean the halo and shoulder openings from both sides with warm water, mild soap and a soft brush.
FAQ
What does the double halo do around this princess center?
Twenty-four round diamonds totaling approximately 0.17 ct build the cushion-square frame around the princess. The shaped outer border increases the visible spread while keeping the 5.5 × 5.5 mm reference center clearly square.
How are the corners of the princess diamond held?
Four prongs secure the center at its corners. The photographed 1.00 ct diamond sits inside the surrounding pavé frame without additional prongs crossing its straight sides.
What do the twisted shoulders add to the design?
Fourteen round diamonds totaling approximately 0.08 ct continue the pavé into the shoulders. Diamond-set sections cross with polished and milgrain-edged metal to carry the pattern away from the halo.
How high does the 1 ct reference setting sit?
The photographed head is approximately 7.00 mm high. The selected center weight determines the final proportions as the setting scales for larger princess diamonds.
How should I clean the double halo and twisted pavé band?
Use warm water, mild soap and a soft brush from both the top and underside. Pay particular attention to the spaces behind the 38 accent diamonds and along the twisted shoulders where residue can collect.
