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 center stone is a single (1) marquise brilliant cut lab grown diamond weighing exactly 0.5 carats. It features an E-F color grade (colorless) and a VS clarity grade, ensuring an eye-clean table with no inclusions visible to the naked eye. The diamond is cut to an Excellent grade by specialized cutters in our Surat facility. The elongated boat silhouette of the marquise geometry optimizes visual surface density, causing a 0.5-carat weight to present a larger face-up area than a traditional round brilliant of identical carat mass. This gemstone comes accompanied by an independent international certification from the International Gemological Institute (IGI) to verify its 4Cs criteria.
THE SETTING:
The center marquise diamond is secured in a classic north-south configuration using a specialized two-prong setting architecture. The pointed tips of the marquise shape are shielded by protective white gold V-prongs, which prevent structural chipping and secure the fragile stone corners without covering the central facet structure. The ring incorporates an open gallery basket beneath the center stone girdle. This open wire framework maximizes light entry from the profile angles, allowing optimal internal light return through the pavilion facets. The setting is seamlessly integrated into a smooth, high-polish D-profile plain shank with zero shoulder accents.
METALS AND FINISH:
The standard configuration is manufactured using solid 14K yellow gold (585 purity, containing 58.5% pure elemental gold) paired with white gold prongs for an optimal two-tone aesthetic that maintains a neutral color backdrop behind the colorless stone. The ring can also be ordered in premium 18K gold (750 purity, containing 75% pure gold) for a richer gold saturation, durability-focused 10K gold (417 purity), or ultra-dense, hypoallergenic Platinum 950. All metal options feature a uniform mirror high-polish finish as the standard production benchmark, with satin/brushed and matte finishes available upon customer request.
CUSTOMISATION AND ORIGIN:
Customization options include loose gemstone selections spanning standard carat tiers: 0.25ct, 0.50ct, 0.75ct, 1.00ct, 1.25ct, 1.50ct, 2.00ct, 2.50ct, and 3.00ct+. Available color grades cover the D–I range, and clarity can be customized across the VVS1–VS2 eye-clean spectrum. Ring sizes are tailored to exact finger measurements. This design is highly favored for traditional Indian engagement ceremonies and pre-wedding festivities due to its subtle, low-profile daily wear utility. Both transaction paths are supported; our technical workshop team confirms exact specifications via WhatsApp and email within 24 hours of checkout. Production requires 15-35 business days from final confirmation.
“Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.”
