THE STONE(S)
The centerpiece architecture comprises a seamless ring of 21 emerald cut lab grown diamonds totaling an exact weight of 5.00 carats. Each individual step cut stone ranges from 0.23 to 0.29 carats and measures 4.25 x 3.0 x 2.05 MM, delivering balanced, elongated rectangular proportions. These stones exhibit clean parallel faceting planes characteristic of masterfully engineered step cuts, producing linear mirror flashes that distinctively contrast with the multi-directional sparkle of traditional brilliant cuts. Graded within the premium EF color and VS clarity tiers, these diamonds are verified 100% eye-clean, ensuring that no internal inclusions disrupt the vast, open tables or the rhythmic internal “hall of mirrors” reflection. Every stone group component undergoes advanced Chemical Vapor Deposition (CVD) or High-Pressure High-Temperature (HPHT) synthesis, and the finished assembly is accompanied by independent diamond grading certification from IGI or SGL to validate its high gemological standing.
THE SETTING
The physical assembly employs a heavy-duty shared-prong pavé setting framework. By forcing adjacent emerald cut stones to share structural metal claws, this layout minimizes the visible surface footprint of the alloy while maximizing stone density and side-angle pavilion visibility. The open under-carriage gallery features dedicated rectangular back-plate light windows aligned with each diamond’s lower pavilion facets. This geometric exposure permits optimal light transmission from multiple angles, allowing ambient light to pass cleanly through the step-cut steps and refract back through the crown. The shared claws are precisely rounded and burnished over the stone girdles at equidistant perimeter points, creating a smooth, catch-free exterior that shields the fragile corners of the rectangular steps against everyday impact.
METALS AND FINISH
Engineered as standard in solid Alloy 585 (14K White Gold) containing 58.5% pure elemental gold, this configuration balances precious metal density with excellent tensile strength for daily wear. The outer and inner surfaces receive a meticulous high-polish mirror finish, amplifying the reflective qualities of the white gold backdrop. For alternative lifestyles and preferences, the piece can be tailored in high-hardness Alloy 417 (10K Gold) for active durability, Alloy 750 (18K Gold) for deep precious metal purity, or non-tarnishing Alloy 950 (Platinum 950), which provides a dense, naturally hypoallergenic structural foundation requiring zero rhodium plating over its operational lifecycle.
CUSTOMISATION AND ORIGIN
Each eternity ring is custom-tailored to the user’s exact quarter- or half-size international measurements. Beyond the standard 5.00 CTW tier, our design workshop provides access to calibrated solitaire scales ranging from 0.25ct up to 3.00ct+ options across standard catalogs. Under Path A, once a digital checkout is finalized, our production desk initiates contact via WhatsApp or email within 24 hours to verify and sign off on exact sizing and metal specifications before manufacturing. The dedicated precision manufacturing timeline requires 15-35 business days from the date of specification validation. This architectural piece serves beautifully as a milestone wedding anniversary band or a high-impact stacking ring. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
