A cushion cut lab grown diamond cathedral halo engagement ring from Signora Jewels.
A 5.80 × 5.80 mm cushion center weighing approx. 1.00 ct sits in a Four-Prong Halo, with 50 round accents totaling approx. 0.37 ct. Approx. 1.37 ct total.
Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.
Choose your preferred metal from the options on this page.
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.

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.
