Technical Archive: The 0.50ct VS1 Square Modified Brilliant Cut. Build No. 001
The Foundation: GIA Sourcing
Every 1V1 commission begins with a singular, documented asset. For our first technical build, the focus was balanced performance. We meticulously sourced a 0.50ct G Color Square Modified Brilliant, GIA-certified as VS1 Clarity. While the market is saturated with commercial-grade inclusions, a VS1 rating ensures a 'very slightly included' profile that remains eye-clean, offering a high-performance stone for this initial architectural study.
The 1V1 Ethical Mandate
Provenance is as critical as technical specification. From this first commission onwards, we have operated a strict procurement policy:
• Conflict-Free: Every stone is sourced through high-integrity, non-conflict channels.
• Ethical Integrity: We only utilize suppliers who adhere to the highest global ethical standards.
• GIA Certified. ALWAYS. We do not negotiate on third-party verification. A 1V1 diamond is a documented asset, never a subjective claim.
The Architecture: Heavy-Gauge Engineering
A stone of this profile requires a structural foundation to match. For this build, we utilized 18ct White Gold heavy-gauge components—including a 4-claw double gallery collet and a precision heavy knife-edge shank. By selecting "Heavy" settings over standard, lightweight commercial castings, we ensured lifelong structural integrity and maximum light return for the square brilliant cut.
The 1V1 Philosophy: Engineering the Singular
In an industry defined by mass-market collections and commercial-grade standards, 1V1 LONDON operates on a different frequency. We do not "stock" jewellery; we engineer singular assets.
Our process is a 1:1 collaboration between the raw, earth-mined miracle of a diamond and the precision of modern architecture. Whether commissioned through our London consultation space or developed within our Newcastle technical atelier, every piece we create begins with a technical brief, not a sales pitch.
The Technical Archive (which follows this entry) is our commitment to transparency. We document the transition from the "Foundation" of GIA-certified sourcing to the "Architecture" of the CAD-engineered frame, and finally to the "Completion" of a hand-finished masterpiece.
We invite you to explore our process. This is the standard of 1V1 LONDON. This is the engineering of the singular.
The Architecture
The Engineering: 9ct Heavy-Gauge Assembly
A diamond of this specific profile requires a calibrated foundation. Following our technical review of the 0.50ct VS1 Square Brilliant, we move to the physical architecture. At 1V1 LONDON, we reject standard commercial castings. This first commission was engineered using precision 9ct White Gold components with a total assembly weight of 1.79 grams.
The Component: 4-Claw Double Gallery Collet
• Specification: 9ct White Gold.
• The 1V1 Standard: We selected the Double Gallery profile for structural rigidity and to ensure maximum light entry to the pavilion of the square cut. Even at a 0.50ct scale, the "Heavy" gauge setting provides a permanent, secure grip that far exceeds the lifespan of lightweight retail alternatives.
The Foundation: Heavy Knife-Edge Shank
• Specification: 9ct White Gold / 1.79g Total Weight.
• The 1V1 Standard: The "Knife-Edge" geometry provides a sharp, sophisticated aesthetic. By maintaining a 1.79g weight for the assembly, we ensure the shank resists the warping and thinning common in mass-produced high-street jewellery.
The Integration & Hallmarking
The marriage of the 0.50ct Square Brilliant to this 9ct architecture defines the 1V1 standard. This piece carries the UK Sponsor’s Mark 'ONE', officially hallmarked at the Edinburgh Assay Office. It is the transition from a documented asset to a wearable piece of British engineering.
The Completion
The Final Assembly: Precision Integration
The final phase of a 1V1 commission is the precise integration of the 0.50ct VS1 Square Brilliant into its 9ct heavy-gauge architecture. This is not a mass-production process; it is a clinical assembly where every claw is hand-set to ensure the integrity of the stone is protected and showcased with maximum light return.
The Mark of Authority: UK Hallmarking
The 1V1 Standard: Every piece that leaves the house carries the legal and physical proof of its purity. Beyond the GIA certification of the diamond, the metal itself is independently tested and hallmarked. For this commission, the Edinburgh Assay Office verified the 9ct White Gold, providing the 'ONE' Sponsor Mark as a permanent guarantee of quality.
Technical Hand-Over
A 1V1 commission is delivered as a complete technical dossier. This includes:
• The Original GIA Laboratory Report.
• The Technical Specification of the build (1.79g Assembly).
• The Certificate of Authenticity.
From Intention to Action
We do not just create jewellery; we document the creation of an asset. This concludes the technical review of our foundational 0.50ct VS1 Square Modified Brilliant commission.
