At a glance
A radiant cut lab grown diamond three-stone engagement ring from Signora Jewels.
A 6.60 × 5.40 mm radiant center weighing approx. 1.01 ct sits between two 4.20 × 2.60 mm kite diamonds totaling approx. 0.24 ct. Approx. 1.25 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 pairs the 1.01 ct radiant center with two kite cuts that point directly into its long sides. The three stones sit in separate open settings, so their outlines stay visible instead of blending into one block of metal.
Four rounded prongs hold the 6.60 × 5.40 mm center. The plain comfort shank leaves the top uncluttered, while the tapered kite diamonds bridge the change from the rectangular center to the narrow band. From the side, the open gallery gives a brush room beneath every stone.
Design highlights
- 1.01 ct radiant cut center diamond
- Two kite cut side diamonds totaling approx. 0.24 ct
- Four-prong center setting
- Open three-stone gallery
- Plain comfort shank
- Approx. 1.25 ct total across 3 diamonds
The kite cuts are the working detail here: their sharp outer points continue the center’s clipped-corner geometry without adding pavé. Browse more three-stone rings, compare cuts in the diamond stone guide, or review metals in the metal guide.
About Lab Grown Diamonds
A radiant cut combines a rectangular outline with a brilliant-style facet pattern, producing smaller flashes across the center. The kite side stones return light differently, with longer reflections that draw the eye inward toward the 1.01 ct center.
Metal, Care & Fit
White Gold and Platinum keep the three stones visually connected, while Yellow or Rose Gold outlines each diamond more clearly. Clean between the center basket and the kite settings with warm water, mild soap and a soft brush. The plain lower shank sits smoothly beside most straight wedding bands.
FAQ
What do the kite side diamonds add to this ring?
The two kite cuts add approx. 0.24 ct and taper the design from the 6.60 × 5.40 mm radiant center into the plain shank.
Are the radiant center’s corners protected?
Four rounded prongs sit at the clipped corners of the center, holding the stone without covering its rectangular outline.
Will this ring stack with a straight wedding band?
The plain comfort shank provides a straightforward stacking surface, though the raised three-stone setting can leave a small gap beside some bands.
How should the open three-stone setting be cleaned?
Brush beneath the radiant basket and behind both kite diamonds, where lotion and soap collect around the open gallery.

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.
