Where Hip-Hop Culture
Meets Fine Craftsmanship

Treasure Box Jewellers was born from a genuine obsession — not just with jewellery, but with what jewellery means. Growing up surrounded by hip-hop culture, we were captivated by the way a watch or a chain could tell a story: of ambition, of achievement, of identity.

But we were equally drawn to the other world — the world of fine diamonds, hallmarked gold, and pieces crafted to outlast generations. We didn't see a contradiction. We saw an opportunity.

From our home in the heart of Hatton Garden, London's historic jewellery quarter, we set out to bridge those two worlds: creating and curating pieces that carry cultural weight and the integrity of true fine jewellery. Pieces that celebrate life's most unforgettable moments.

"Designed to celebrate life's most unforgettable moments."

Our Values

These aren't statements on a wall. They are the decisions we make every day — in every stone we select, every piece we design, and every client we serve.

01

Ethical Sourcing

Every diamond, every metal, every gemstone is responsibly acquired. We work only with suppliers who share our commitment to fair labour, conflict-free stones, and traceable supply chains.

02

Uncompromising Craft

We believe quality is non-negotiable. Whether it's a bespoke engagement ring or a pre-owned Rolex, every piece passes through the same rigorous standard of inspection and care before it reaches you.

03

People First

From the artisans who craft your piece to the client who wears it — people are at the centre of everything. We take time to listen, to understand, and to create something that genuinely matters.

04

Built to Endure

A piece of jewellery should outlast trends, seasons, and years. We design and source with longevity in mind — because the most meaningful things in life are made to be passed down, not replaced.

Jewellery crafting

From Idea
to Heirloom

Our bespoke process is collaborative, transparent, and built around your vision. Here's how we bring your dream piece to life.

01

Share Your Ideas

Tell us everything — your inspiration, budget, occasion, and style. Bring sketches, references, or simply a feeling. There are no wrong starting points.

02

Sketch & Design

Our craftsmen translate your vision into detailed sketches and, where needed, 3D renders. You'll see exactly how your piece will look before anything is made.

03

40% Deposit

A non-refundable 40% deposit confirms your order and covers initial materials and workshop time. This protects both the artisan's work and your commission.

04

Final Approval

Before completion, we present your piece for final sign-off. At this stage the remaining balance is settled and your piece enters its finishing stage.

05

Delivered to You

Your finished piece arrives in our signature Treasure Box packaging, with certification, care instructions, and a lifetime of our support behind it.

Please note: bespoke and custom items are non-refundable. The 40% deposit is non-refundable upon design sign-off. For standard items, our 7-day return policy applies — see our Terms & Conditions for full details.

Yes — all eligible standard orders over £500 are shipped free using fully insured, tracked couriers. This does not apply to bespoke commissions, which are arranged separately.

Absolutely. Every pre-owned timepiece is independently authenticated before being listed for sale. All jewellery carries our Treasure Box authenticity documentation, and diamonds come with independent certification where applicable.

Bespoke & Custom

Once you approve the final design, a 40% deposit is required to begin production. This deposit is non-refundable as it covers materials procurement and workshop time. The remaining 60% is due upon final approval before your piece is delivered.

Most standard bespoke commissions are completed within 6–8 weeks. Complex pieces or those requiring rare stones may take 10–16 weeks. We'll give you a clear timeline during your initial consultation and keep you updated throughout.

Minor revisions can be accommodated before the deposit is paid. Once production has begun, significant changes may incur additional costs or extend the timeline. We encourage thorough review at the design stage to avoid this.
