Lab Grown Diamond Round Brilliant Architectural Split-Shank Two-Tone Ring 2.61 Carat | Primira Luxury

The Stones

The center of this modernist design features a substantial 2.61 carat round brilliant laboratory-grown diamond, independently certified with an Excellent cut grade. Featuring an F color grade and eye-clean VS1 clarity, the stone displays exceptional internal light transmission, completely free of visible inclusions. The geometric orientation of the facets maximizes scintillation across the crown. Flanking the center stone, the split-shank shoulders are mapped with 28 round brilliant lab grown diamond accents totaling 0.42 carats (EF color, VS clarity). These micro-pavé accents form a dense, continuous field of light that frames the central stone without competing with its optical dominance.

The Setting

Engineered for both high-impact visual presence and daily security, the setting features four prominent, square-faced structural corner prongs. These heavy-profile white metal prongs encase the girdle at critical stress points, lifting the stone into an elevated cathedral gallery. The open-aperture lower gallery is mechanically optimized to allow maximum light entry from underneath the pavilion, accelerating internal reflections. The gallery structure splits dynamically at the shoulders, utilizing a sweeping architectural under-rail that provides a rigid structural apex while maintaining a low-profile feel on the finger.

Metals and Finish

This piece is composed of a distinctive two-tone architecture, pairing a highly polished 14K yellow gold inner core (585 purity code) with white metal stone-anchoring components. The yellow gold inner under-rail saturates the warm geometric accents of the inner shank, while the white prongs preserve the colorless profile of the center stone. For active lifestyles or alternative preferences, the ring can be ordered in 10K gold (417) for maximum scratch resistance, 18K gold (750) for an enhanced alloy hue, or 950 Platinum—the densest metal choice for ultimate prong security.

Customisation and Origin

Every ring is built to order and completely customizable. Following checkout on primiraluxury.com, our workshop team will contact you within 24 hours via WhatsApp and email to confirm your exact specifications before manufacturing begins. During this consultation, you can alter the stone carat weight (standard tiers from 0.25ct to 3.00ct+), color grade, clarity tier, ring size (including quarter and half sizes), band width, or select a hand-faceted moissanite center stone alternative.

Production requires 15–35 business days (up to 45 business days in rare sourcing or third-party lab certification scenarios) to ensure precise structural calibration. This architectural split-shank layout is balanced specifically to prevent the top-heavy spinning common in large-carat rings, keeping the center diamond perfectly centered during continuous daily wear. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
