1V1 - means every piece is crafted just for you – from scratch, not from a pre-made mould. We work with you to refine the design, select your metal and diamond, then handcraft everything in London’s Hatton Garden district. No two pieces are the same – your jewellery will be as unique as your story.

One-of-a-kind engagement rings and high jewellery, designed and crafted to your exact specifications.

GIA-Certified Diamond Sourcing

Individually sourced natural diamonds, independently certified and selected to your required criteria.

Custom Wedding Bands

Handcrafted bands tailored to complement engagement rings or created as standalone commissions.

Private Consultation

Discrete design consultations in London, Manchester, Newcastle Upon Tyne, or via secure remote appointment.

It means the piece is created specifically for you after consultation.

It is not pre-manufactured or held in stock.

Each ring is:

    •    Crafted to your selected specifications

    •    Produced in your chosen metal

    •    Set with a specific certified diamond

No two commissions are identical unless requested.

Different metals have different:

    •    Market values

    •    Density and weight

    •    Durability characteristics

    •    Manufacturing complexity

For example:

    •    Platinum is denser and heavier than gold → higher material cost.

    •    18ct gold contains more pure gold than 14ct → higher value.

The final price reflects material cost and craftsmanship.
