Bespoke Jewellery in Mayfair

From Sketch to Stone

Create the ring or jewel you can’t find anywhere else with Pragnell’s bespoke jewellery service in Mayfair. Your journey begins in our townhouse showroom with a private consultation, where designers sketch ideas inspired by your story and chosen stones. Every stage—design, crafting and final fitting—is completed in Britain by master artisans, ensuring a beautiful piece, made to last.

Whether commissioning a one-of-a-kind engagement ring or re-imagining an heirloom, Pragnell’s bespoke process offers a truly personalised luxury experience. To begin creating your unique piece, book an appointment with our Mayfair team.

From Initial Consultation to Finished Jewel

STEP 1

Initial Consultation

Begin with a private consultation with a member of the Mayfair team to discuss your ideas, preferred style, lifestyle and budget. Existing or inherited jewellery can also be reviewed, helping to inform the design and direction of your bespoke commission.

STEP 2

Design Development

Our designers develop the initial concept through sketches, considered design proposals and a visual 3D model. Explore a selection of carefully selected diamonds and coloured gemstones before refining the design and agreeing the final specifications.

STEP 3

Crafting in Britain

Once approved, the design is entrusted to Pragnell's British workshops. Designers, goldsmiths and gem setters work together using traditional techniques to craft, set and finish the piece by hand, ensuring exceptional quality, precision and beauty.

STEP 4

Final Fitting and Presentation

The completed piece is presented at the Mayfair showroom, where a final fitting can be arranged if required. The team will explain the craftsmanship behind the design, provide guidance on its care, and ensure every detail has been finished to the highest standard.

A Historic London Location

Nestled on prestigious Mount Street, the Pragnell showroom in Mayfair reflects a long standing-heritage in London’s jewellery trade, with craftsmanship roots extending back to the early 1800s through historic houses such as Philip Antrobus and Waters & Blott.

Pragnell’s heritage includes its connection to Queen Elizabeth II’s 1947 wedding jewellery—her diamond engagement ring and bracelet were originally designed by Philip Antrobus—cementing a legacy of royal-level craftsmanship. This historic lineage continued when Pragnell acquired the Antrobus archives.

On 21 November 2017, exactly seventy years and a day after the royal anniversary, Pragnell opened its Mayfair townhouse showroom at 14 Mount Street, marking a modern chapter in the family’s enduring London presence.
