A round lab grown diamond vintage halo engagement ring from Signora Jewels.
A 1.00 ct round brilliant center measuring approximately 6.4–6.5 mm, held by four prongs inside a geometric halo with 34 round halo and band accents totaling approximately 0.26 ct. Approx. 1.26 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 your preferred metal from the options on this page.
Signora Jewels sets the 6.4–6.5 mm round center inside a halo that refuses to stay perfectly circular. The outer edge rises into pointed sections around the diamond, with milgrain tracing the perimeter and small rounds filling the space between the center and that geometric border.
The pattern continues into the shank. Two polished strands twist through pavé-set sections on each shoulder, reaching approximately 3.50 mm wide near the head before settling into a 2.10 mm lower band. The result is detailed from straight above without adding another row of diamonds around the center.
Design highlights
- 1.00 ct round brilliant center measuring approximately 6.4–6.5 mm
- 18 round halo diamonds totaling approximately 0.16 ct
- 16 round shoulder diamonds totaling approximately 0.10 ct
- Geometric halo outlined with fine milgrain detail
- Twisted pavé shoulders measuring approximately 3.50 mm near the setting
- Approx. 7.00 mm setting height with a 2.10 mm lower shank
The halo does two jobs at once: the small rounds extend the visible spread of the 1.00 ct center, while the pointed outer frame gives the ring its vintage geometry. The twisted shoulders carry that detail away from the head instead of stopping abruptly at the halo.

About Lab Grown Diamonds
The round brilliant center measures approximately 6.4–6.5 mm across at 1.00 ct. Thirty-four smaller round diamonds repeat the same circular shape through the halo and shoulders, but at much smaller scale, creating a clear size progression from the center into the surrounding pavé.
Metal, Care & Fit
The reference construction uses approximately 5.80 g of 18K gold before the diamonds are set. Yellow and rose gold make the milgrain frame and twisted strands easier to distinguish, while white gold and platinum keep the pavé visually continuous with the diamonds. Use warm water, mild soap and a soft brush around the halo and twisted shoulders, working from the underside as well as the top.
FAQ
What does the geometric halo do around the 1 ct center?
Eighteen round diamonds totaling approximately 0.16 ct surround the 1.00 ct center. The outer metal edge rises into pointed sections, so the halo reads as a shaped vintage frame rather than a simple circle.
How are the diamonds arranged on the twisted shoulders?
Sixteen round diamonds totaling approximately 0.10 ct run through the shoulder design. Pavé-set sections cross with polished metal strands to create the twisted pattern visible on both sides of the halo.
How high does this ring sit?
The setting is approximately 7.00 mm high. That height accommodates the center and surrounding halo while the shoulders rise directly into the geometric frame.
Can this halo ring be stacked with a straight wedding band?
The geometric halo extends beyond the approximately 2.10 mm lower shank. A straight band can leave a small gap near the head, so a contoured band is the closer visual match.
How should I clean the milgrain and pavé sections?
Use a soft brush with warm water and mild soap around the halo edge and twisted shoulders. Brush gently from underneath as well, since the small spaces around 34 accent diamonds can hold lotion and residue.

Answers last updated August 2, 2026
When will my order ship?
Standard listed pieces are made to order with an estimated dispatch of 7 business days. Use the product-page estimate when it is more specific and the timing confirmed after ordering. Delivery timing begins after dispatch and varies by destination and carrier service. Fully custom commissions follow the production schedule confirmed with their approved specifications or CAD.
When is insured worldwide delivery free?
Orders of US$500 or more receive free express, insured and tracked worldwide delivery. Below US$500, express, insured and tracked worldwide delivery is charged at the fixed rate shown at checkout.
Will I have to pay import duties?
For every destination available at checkout, Signora prepays applicable import duties and import taxes. Customers should not be asked to pay those import charges again on delivery.
What certificate comes with my jewelry?
Every finished piece includes a Signora Jewelry Certificate. Each selected individual lab-grown center or primary diamond of 0.50 ct or above includes an IGI grading report. Below 0.50 ct, IGI can be arranged by custom request. Custom moissanite and gemstone selections include GRA documentation, with the exact scope confirmed in the approved specifications. The product page or approved specifications state the exact laboratory, report type and scope.
Can I return a made-to-order listed design?
Standard listed products are eligible for return within 30 days after carrier-recorded delivery when unworn, unused and in their original condition, with the original packaging and included documents. Normal listed choices such as metal, stone carat, chain or bracelet length, an extended ring size, or complimentary engraving do not by themselves make an item Final Sale. A sale or discount also does not imply Final Sale; only an item explicitly classified as Final Sale follows the non-returnable exclusion.
How are fully custom orders handled?
A fully custom commission is different from a listed made-to-order design. After its specifications or CAD are approved, a normal change-of-mind return does not apply. Manufacturing defects remain reviewable. Signora may accept an exceptional non-defect return case by case; documented labor and genuinely non-recoverable costs may be deducted, but these deductions are not a restocking fee.
