Lab Grown Diamond Radiant Split-Shank Halo Ring in 18K White Gold (1.23 CTW)

The Stones

The focal engineering of this piece relies on a high-saturation, 1.01 carat vivid orange radiant cut lab grown diamond. Possessing an eye-clean VS2 clarity profile, the emerald-cut variant facet pattern creates steep internal light reflections that concentrate the warmth of the orange hue. Encircling the primary stone is a brilliant halo hosting 14 round brilliant lab grown diamonds, while an additional 16 round brilliant stones run along the split shoulders. These accent stones feature an E-F color tier and VS clarity range, providing a stark, colorless contrast that emphasizes the primary stone’s rich color profile. Every stone group is independently verified, with the center diamond carrying a laser-inscribed IGI certification report number on the girdle.

The Setting

The setting framework utilizes a four-prong corner configuration to anchor the 7.50 x 4.85 MM radiant center stone securely at its high-stress points. This sits inside an elevated, open four-pillar cathedral basket under-gallery structure, creating a high-clearance window beneath the culet to maximize ambient light entry through the pavilion facets. The accent stones are hand-set into a flush micro-pavé arrangement along the halo frame and split-rail shoulders, using tiny, polished metal beads to ensure a continuous field of reflection while maintaining a snag-free surface profile.

Metals and Finish

Forged in premium 750-purity 18K white gold, the alloy composition is engineered for daily structural integrity, providing rigidity to hold the dual-rail split shank in place over extended wear. The metal surfaces are coated in a high-polish rhodium plating, yielding a highly reflective, neutral backdrop that prevents color bleeding into the near-colorless accent diamonds. The split-shoulder band tapers gracefully into a solid, heavy lower shank calibrated to withstand reshaping forces from daily manual activity.

Customisation and Origin

Every order follows a strict production protocol. Within 24 hours of checkout on primiraluxury.com, our workshop team confirms your precise specifications via WhatsApp and email before any metal casting begins. During this window, you can adjust the stone carat weight, clarity tiers, metal selection (including 10K, 14K, 18K gold, or 950 Platinum), ring sizing, and custom band finishes. Production requires 15–35 business days, as each multi-stone split-shank piece is manufactured to order.

Returns are accepted only where the delivered product is materially different from confirmed specs, damaged in transit, or the wrong item shipped; requests must be filed within 7 calendar days of delivery in original packaging with all documentation. For value recovery, our structured buyback program provides invoice value minus making charges, applicable taxes, gateway charges, and processing fees, with gold valued at the prevailing market rate on the evaluation date. The structural geometry of the split shank provides an exceptionally stable fit on the finger, preventing top-heavy spinning—making it an ideal choice for an alternative engagement statement or identity-driven piece.
