Custom & Bespoke Lab-Grown Diamond Jewellery

Bespoke commissions

A piece made for you, exactly as you imagined it.

Whether you have a Pinterest board full of inspiration, a single screenshot of something you love, or just a feeling for the kind of piece you want — we’ll help you turn it into a real piece of fine jewellery in solid precious metal and lab-grown diamonds.

What we can make for you

Almost anything in fine jewellery. The most common custom commissions we take on:

  • Engagement rings — solitaire, halo, trilogy, vintage-inspired, modern minimal, set with the lab-grown diamond shape and carat of your choice
  • Wedding bands and eternity rings — plain, pavé-set, half-set, full-set, matched to an existing engagement piece if needed
  • Tennis bracelets and tennis necklaces — round, princess, emerald, pear, baguette, or mixed-cut lab-grown diamond patterns in any length
  • Pendants and statement necklaces — solitaire, halo, cluster, initial, name, or signature design
  • Earrings — studs, hoops, drops, hugger style, in any size up to substantial statement pieces
  • Redesigns of inherited jewellery — we can work with stones you already own or repurpose materials from existing pieces
  • Anniversary, milestone, and gift commissions — designed around a date, an initial, a meaningful detail
  • Matching sets — pieces designed to wear together (ring + band, pendant + earrings, etc.)

If you’re not sure whether what you want is possible — send us the enquiry anyway. The answer is almost always yes.

Custom design deposit

How the price and deposits work

Asking is free. After we review your enquiry, we’ll give you an estimated price before you pay anything.

When you’re happy with the estimate, a £100 design deposit starts your CAD design. It’s taken off the price of your piece.

Your CAD design includes up to three rounds of changes, and comes with your detailed written quote.

Once your design and quote are approved, a 50% production deposit starts production, and your £100 counts towards it. The final balance is due before dispatch.

If you choose not to proceed once your CAD design has been made, the design deposit is non-refundable as the design work will have been carried out. See our Custom Orders Policy for full terms.

How the process works

Step 01

Tell us your idea

Send a reference image, a Pinterest save, or a short description. The more you give us, the more accurately we can quote — but a single photo of a piece you love is enough to start.

Step 02

We review and respond

Within two working days, we’ll come back with design notes, material options, lab-grown diamond suggestions, and any questions we need to answer before quoting. We’ll also give you an estimated price at this stage.

Step 03

Design deposit & your CAD design

When you’re happy with the estimate, a £100 design deposit starts your CAD design, with up to three rounds of changes. It’s taken off the price of your piece. You also receive a detailed written quote covering metal, lab-grown diamond specification, sizing, lead time, payment stages and final price.

Step 04

Approve and pay deposit

Once you’re happy with the design and quote, a 50% production deposit secures your piece into production. Your £100 design deposit counts towards it.

Step 05

Production begins

Your piece is made to order in your chosen metal and lab-grown diamond specification. We’ll keep you updated through key stages and can share progress images on request.

Final payment and delivery

Final balance is settled before dispatch. Your piece is sent tracked and signed for, and presented in branded packaging.

Where to find inspiration

You don’t need to arrive with a finished design. Most of our best commissions start with a single image. If you’re not sure where to look:

  • Pinterest — search “lab-grown engagement ring”, “tennis bracelet inspiration”, “oval halo ring”, or any specific style you’re drawn to. Save a few you love and send us the board link or screenshots.
  • Instagram — screenshot pieces from fine jewellery designers, celebrity engagement rings, or vintage pieces. Send us the images.
  • Existing pieces you own or have seen — a photo of an heirloom ring, a piece in a shop window, or something a friend wears. We can work from a clear photo.
  • Our own collections — browse the rings, necklaces, bracelets, pendants, and earrings and tell us which existing piece you’d like adapted (different metal, different lab-grown diamond, different size).
  • Sketches or descriptions — if you can describe it in words, we can usually visualise it.

What we’ll ask you about

You won’t know all the answers yet — that’s our job. But here’s what we’ll work through together at quote stage:

Metal

Solid 925 sterling silver, or 14kt or 18kt gold in yellow, white, or rose.

Not sure? We’ll guide you based on the piece, budget, and how you’ll wear it.

Lab-grown diamond shape and size

Round, oval, emerald, pear, princess, marquise, cushion, or radiant. Carat weight to suit your budget and the piece.

We’ll recommend specifications that match your inspiration image.

Lab-grown diamond quality

Every diamond we set is lab-grown, D–F colour and VS1 clarity or better. A centre stone of 1.00ct or above comes with an individual IGI grading report as standard, at no extra cost and with no added lead time.

Tell us your budget and we’ll suggest the best shape and carat weight for it.

Sizing

Ring size, bracelet length, chain length, pendant size. UK or US sizing accepted.

If you don’t know yet, we can advise on sizing.

Setting style

Prong, bezel, halo, pavé, channel, tension, illusion. We’ll match it to your reference.

A photo of the setting style you like is the easiest reference.

Budget

Optional but useful. Helps us recommend the right combination of metal and lab-grown diamond specification.

Even a rough range is helpful.

Timescale

Our usual production lead time is around four weeks in sterling silver or gold including UK hallmarking where required, from written approval and cleared production deposit. More complex pieces may take slightly longer.

If you have a target date, mention it — we’ll be upfront if it’s tight.

Personal touches

Engraving, hidden details, mixed metals, second stones, or matching pieces.

Tell us the story behind the piece if there is one — it often shapes the design.

Pricing

Custom pieces are quoted individually. Final price depends on metal choice, lab-grown diamond specification, carat weight, sizing, design complexity and any hallmarking required.

Every quote is provided in writing before the production deposit is taken. The quote breaks down each element so you can see exactly what affects the price — and adjust if you want. Unless the quote says otherwise, it is valid for 7 calendar days because metal and lab-grown diamond prices can move.

A 50% production deposit secures your piece into production (your £100 design deposit counts towards it), with the balance due before dispatch.

We send secure Shopify invoices or checkout links for the production deposit and final balance, so every payment remains attached to your custom order.

Returns on custom pieces

Because custom and bespoke pieces are made specifically to your specification, they may not be eligible for change-of-mind cancellation once design work, sourcing, CAD work, stone sourcing, casting, setting, hallmarking or production has started.

We mitigate this by confirming every quote in writing before deposits are taken, and working closely with you at the design and approval stage. Faulty or incorrectly-supplied pieces are always covered under the Consumer Rights Act 2015 — see our Returns & Refunds Policy and Custom Orders Policy for full terms.
