4.64 ctw Lab Grown Diamond Radiant Split-Shank Solitaire Ring

The Stone(s)

The focal point of this structural silhouette is an elongated, 4.40 carat radiant-cut lab grown diamond. This particular center stone exhibits the parallel linear facet patterns characteristic of traditional step-cuts, blended with a brilliant faceting pattern across the pavilion to optimize light return. Graded F color and VS1 clarity by independent gemological laboratories, the stone is entirely eye-clean and sits within the colorless premium tier. Running down the shoulders of the band are 24 round brilliant lab grown diamonds totaling 0.24 carats. These accent stones are graded EF color and VS clarity, ensuring a uniform field of light that complements the primary radiant diamond. Every diamond is verified via a laser-inscribed report number on the girdle, matching its official third-party grading documentation.

The Setting

The center diamond is held by four corner-positioned double-claws that securely anchor the blocked corners of the radiant cut. This setting architecture lifts the stone into a high-profile cathedral position, supported by an open under-gallery with a geometric basket and an integrated horizontal support rail. This open double-bar design maximizes lateral visibility, allowing light to enter the pavilion from all angles while maintaining structural rigidity. The shank splits widely as it approaches the gallery, creating a dramatic architectural void that provides exceptional lateral stability to the 4.40 carat stone, keeping it perfectly balanced on the finger.

Metals and Finish

This piece is engineered in 14K gold (585 purity) as the standard configuration, providing the ideal ratio of pure gold content to structural durability for high-carat settings. The ring can also be custom-manufactured in 10K gold (417 purity) for maximum scratch resistance, 18K gold (750 purity) for a richer metallic alloy hue, or 950 Platinum for an ultra-dense, naturally hypoallergenic profile that offers the ultimate prong security. The gold components are finished with a high-polish reflective surface, with rhodium-plating applied to the white gold prongs to ensure a perfectly neutral backdrop for the colorless radiant stone.
