Lab Grown Diamond Portuguese Cut Halo Split Shank Ring 1.90 CTW

The Stones

The center of this architecture is a 1.26 carat Portuguese cut lab grown diamond featuring a complex, multi-tiered concentric facet arrangement. With 161 facets—more than double the standard brilliant cut—this antique-inspired geometry creates a dense, highly distributed scintillation field that maximizes movement-based light return. Graded at an exceptional D color and VS1 clarity, the stone is entirely eye-clean. Encircling the center is a uniform halo of 16 round brilliant lab grown diamonds, while an additional 35 round stones form dual rows along the open split shoulders. These 51 accent diamonds total 0.64 carats, carrying an EF color and VS clarity grade to ensure a seamless monochromatic light profile across the entire piece.

The Setting

The setting uses an elevated cathedral framework where four solid claw prongs anchor the 6.43mm Portuguese center stone at the compass points. This layout secures the girdle without obstructing the perimeter facets. The surrounding halo and the split shoulders utilize a shared-prong micro-pavé technique, minimizing visible metal to allow the accent stones to sit tightly packed. The gallery features an open under-rail structure, exposing the pavilion of the center diamond. This design path ensures unobstructed light penetration from beneath, driving maximum optical performance through the upper tiers of facets while remaining structurally resilient against daily wear.

Metals and Finish

Built by default in solid 14K Gold (585 purity code), the alloy balances gold content with the structural hardness necessary to secure a 52-stone composition. The warm undertone of the 14K rose gold provides a contrasting backdrop that accentuates the colorless D-grade center diamond. For alternative preferences, the ring is available in 10K gold (417) for active lifestyles, 18K gold (750) for maximized gold content, or dense 950 Platinum for ultimate prong security and a hypoallergenic profile. All metal options are finished with a high-polish reflective surface across the inner band and structural supports.

Customisation and Origin

Every ring is made-to-order and fully adaptable to individual dimensions. Standard solitaire options span from 0.25ct up to 3.00ct+ on custom request, with color grades available from D to I and clarity from VVS1 to VS2. Following checkout, our workshop team contacts you within 24 hours via WhatsApp and email to confirm your exact ring size, metal choice, and stone configurations before production begins. Standard manufacturing requires 15–35 business days to execute the setting and secure laboratory certification.

The split-shank architecture elevates the halo cluster just enough to allow standard wedding bands to slide flush underneath, making it highly functional as a daily engagement piece. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
