The Founder’s Personal Guarantee

My word is in the metal.

At 1V1 LONDON, we don't hide behind algorithms or drop-shipping warehouses. When you purchase a piece from our collection, you are buying a physical asset that I have personally verified. Every item that is purchased from our signature range is legally hallmarked at the Edinburgh Assay Office (Ref: A338064) and carries my unique 'ONE' sponsor mark.

I guarantee the purity of our gold and the certification of our diamonds. If you have a question, you aren't calling a bot—you are calling me. This is my business, my name, and my personal commitment to your investment.

The Creative Director: Lee Barrett

Design Without Compromise.

Lee Barrett serves as the Creative Director for 1V1 LONDON. With a focus on structural elegance and high-jewellery precision, Lee ensures that every 'Bespoke' commission and 'Signature' piece meets the Hatton Garden standard of excellence. From initial sketch to the final polish, the creative vision is directed by a master of the craft, not a trend-following template.

The Back Room: Administrative & Intelligence

Precision 24/7/365

To ensure 1V1 LONDON operates with the speed of a global institution and the accuracy of a Swiss watch, we utilise a dedicated administrative backbone.

Ola: Our Lead Administrative Secretary. Ola manages & coordinates supply-chain logistics, and ensures that every hallmark registration and GIA dossier is filed with zero margin for error.

Nova: Our Market Intelligence & Data Analyst. Responsible for real-time market strategies which lead to direct better outcomes for our clients ensuring digital compliance.

While I oversee the creation and Lee directs the design, our specialist team handles the logistics, compliance, and data. We move with absolute technical sovereignty, ensuring your order is processed, tracked, and verified to the highest standard.
