A round lab grown diamond halo engagement ring from Signora Jewels.
The photographed design centers a 1.01 ct round brilliant measuring approximately 6.4–6.5 mm in a four-prong setting, surrounded by 20 round halo diamonds totaling approximately 0.18 ct. Approx. 1.19 ct total.
Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.
Each metal color is shown in the photos. Choose a 1 ct, 1.01 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct center and your preferred metal from the options on this page.
Signora Jewels sets the 6.4–6.5 mm round brilliant inside a halo that reads slightly squared at its outer corners. Four prongs hold the photographed 1.01 ct center while 20 smaller rounds circle it, adding approximately 0.18 ct without carrying pavé down the shank.
The plain band is the counterpoint to the halo. It measures approximately 2.00 mm at the bottom and 2.10 mm through the shoulders, then meets a raised open gallery beneath the center. At the reference weight, the setting stands approximately 6.80 mm high.
Design highlights
- Round brilliant center customizable from 1 to 4.5 ct
- 1.01 ct reference center measuring approximately 6.4–6.5 mm
- 20 round halo diamonds totaling approximately 0.18 ct
- Four-prong center setting inside a cushion-outline halo
- Raised open gallery beneath the center for underside access
- Plain approximately 2.00 mm lower shank with no shoulder pavé
The halo concentrates every accent diamond around the center. Twenty small rounds extend its visible spread, but the polished shoulders stop the sparkle at the head, leaving a clean break between the halo and band.

About Lab Grown Diamonds
The round brilliant reference center measures approximately 6.4–6.5 mm across at 1.01 ct. Its circular facet pattern is repeated at a smaller scale by the 20 round halo diamonds, while the cushion-shaped outer edge gives the surrounding frame a subtly squared profile.
Metal, Care & Fit
The reference construction uses approximately 4.70 g of 18K gold before the diamonds are set. Yellow and rose gold create stronger contrast between the halo and center; white gold and platinum keep the frame closer in tone to the stones. Clean through the open gallery with warm water, mild soap and a soft brush so residue does not remain beneath the center or halo.
FAQ
What does the cushion-shaped halo do around the round center?
Twenty round diamonds totaling approximately 0.18 ct surround the center. Their arrangement extends the visible spread of the 6.4–6.5 mm reference diamond while the outer frame gives the ring a softly squared outline.
Why is the band left plain?
All 20 accent diamonds are concentrated around the center rather than running down the shoulders. The approximately 2.00 mm lower shank stays polished and un-set, creating a clear visual break below the halo.
How high does the 1.01 ct reference setting sit?
The photographed setting is approximately 6.80 mm high. Its raised open gallery creates access beneath the center and separates the halo from the finger.
Will a straight wedding band sit beside this halo ring?
The halo extends beyond the approximately 2.10 mm shoulders, so a straight band can leave a small gap near the head. A contoured band follows the projecting halo more closely.
How should I clean beneath the halo?
Use warm water, mild soap and a soft brush through the open gallery. Brush gently beneath the center and around the 20 halo diamonds, where lotion and soap residue can collect.
