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.

Story
The Stones
The focal point of this design is a 1.01 carat laboratory-grown diamond featuring a specialized 161-facet Portuguese cut. This intricate faceting pattern generates a highly dense, geometric light-return matrix across the crown, distinguishing it from standard 57-facet brilliant cuts. Graded at F color (colorless) and VS1 clarity (completely eye-clean), the center diamond is independently evaluated and laser-inscribed. Framing one side of this center stone is an asymmetric crescent composed of 7 round brilliant lab grown diamonds totaling 0.07 carats. These accent stones are selected at an elite EF color and VVS clarity tier, creating a high-dispersion surface field that contrasts against the architectural geometry of the main Portuguese stone.
The Setting
Engineered for a balance of optical access and structural security, the center stone is anchored by four rounded prongs. This structural configuration leaves the crown and upper girdle unobstructed, maximizing lateral light entry into the pavilion. The asymmetric side cluster is built using a low-profile shared-prong pavé setting. This method minimizes the visible metal between the accent stones, creating a concentrated crescent of light along half of the main setting’s perimeter. An open architectural under-gallery features a circular structural base rim that stabilizes the crown assembly while allowing unhindered access for cleaning and maximum light transmission from beneath.
Metals and Finish
This piece is rendered by default in high-polish 585 (14K) white gold, treated with a premium rhodium plating to achieve a neutral, high-reflectivity backdrop that prevents color transfer into the F-grade center diamond. For alternative preferences, the ring can be cast in 417 (10K) gold for maximum scratch resistance, 750 (18K) gold for a richer alloy purity, or hypoallergenic 950 platinum for ultimate weight and prong security. The shank features a classic rounded profile with a smooth, solid back, ensuring comfortable daily wear as the asymmetric setting remains stable on the finger without pivoting.
Customisation and Origin
Every order enters a dedicated manufacturing workflow. Following checkout, our team contacts you within 24 hours via WhatsApp and email to verify your exact specifications before casting begins. During this consultation phase, you can adjust the center stone carat weight (with tiers from 0.25ct up to 3.00ct+), modify the color or clarity profile, alter the band width, or select custom finishes including satin, matte, or hammered textures. Production requires 15–35 business days to accommodate precise diamond setting and third-party laboratory grading.
Crafted in Surat — the city that cuts 90% of the world’s diamonds — and shipped factory-direct.
