Independent Lab Certification (IGI & SGL)
- Third-Party Proof: Every piece is strictly audited and certified by independent global authorities (IGI or SGL).
- Laser-Inscribed: Center gems feature a microscopic lab report serial number etched on the edge for permanent tracking.
- Verified Alloys: Labs verify and stamp the exact metal purity hallmarking alongside the gemstone metrics.
Precious Metal Purity & Skin Safety
- The Nickel-Free Guarantee: Most allergic skin reactions to jewelry are caused by cheap nickel alloys. Our jewelry is 100% nickel-free and lead-free, guaranteeing a clean, rash-free wearing experience even in warm weather.
- Engineered Against Tarnish: Whether you choose our solid 18K, 14K, 10K gold, or our premium Platinum 950, our precious metals are mixed to guarantee they will not oxidize, fade, or discolor over time. You can safely wear your jewelry every single day without losing its rich luster.
- No Green Skin: Because we entirely reject base metals, copper fills, and flash-plating, our jewelry will never tarnish, oxidize, or turn your skin green or grey.
Elite Craftsmanship & Stone Security
- Micro-Prong Precision: Every accent diamond or moissanite is meticulously set under microscopic magnification. Prongs are rounded into smooth, snag-free beads that lock the stones in place without catching on fine fabrics or silk.
- Reinforced Gallery Rails: Our ring mountings and pendant baskets feature integrated structural gallery rails. This architectural design distributes impact shock evenly, preventing center stones from shifting or loosening over a lifetime of wear.
- Artisan Mirror Polishing: Before your piece is set, the entire metal chassis undergoes a multi-stage high-gloss hand polishing process, maximizing internal light reflections and giving the metal a liquid-like mirror shine.
Insured Premium Shipping & Presentation
- Armored Courier Delivery: Your finished heirloom travels through an express, fully insured armored courier network. For your security, a physical adult signature is strictly required upon delivery.
- The Luxury Presentation Vault: To maintain absolute discretion and surprise, the parcel arrives in an unbranded outer box. Inside, it opens into a heavy timber, velvet-lined presentation vault designed to protect and showcase your piece for years to come.

Story
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.
Customisation and Origin
Every ring is made to order and can be configured to your exact specifications. Available center stone tiers range from 0.25ct up to 10ct+, with custom adjustments available for band width, finish, and ring sizing (including quarter and half-size increments). Our standard timeline requires 15–35 business days for production and third-party laboratory certification.
The transaction flow is transparent: following checkout on primiraluxury.com, our engineering team will contact you via WhatsApp and email within 24 hours to confirm your precise specifications before manufacturing begins. Standard shipping across India is free for orders above ₹10,000 via Blue Dart or Delhivery (2–7 business days after dispatch). International standard shipping is free via tracked USPS/India Post (17–19 business days), while insured express shipping via DHL or FedEx (5–7 business days) is available. Returns are accepted within 7 calendar days only if the delivered piece is materially different from the confirmed specifications or damaged in transit; standard made-to-order items are final sale. Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
