A bespoke piece moves through four checkpoints: consultation; design (sketch, CAD and prototype); manufacture (handcrafting or casting); and finishing, which includes hallmarking before collection. You approve the work at each stage, and that hallmark is your legal guarantee the metal is genuine, a point Gov makes plain and something a jeweller like Blackwell Jewellers builds into every commission.
TL;DR:
- Hand fabrication yields a denser, more refined piece but costs more than casting, which is faster and suitable for complex or sculptural designs.
- Revisions during design, especially at the CAD and prototype stages, can significantly extend the timeline and increase costs if multiple changes are made.
- Hallmarking ensures metal purity and authenticity in the UK and must be applied after finishing, with the assay details verified before delivery.
- The total cost of a bespoke piece varies widely based on metal weight, design intricacy, gemstones, and revision counts, with longer and more complex projects costing more.
- Proper documentation at every stage, including written approvals and clear policies on changes, protects both the client and the jeweller from misunderstandings.

The main stages of a bespoke commission
Right, let’s get the lay of the land before we get into the weeds. A bespoke commission isn’t one big mysterious process, it’s a handful of distinct stages, each with its own deliverable and its own decision point.
- Consultation: you talk, the jeweller listens, and together you land on a brief covering style, budget and materials.
- Design development: sketches turn into CAD files, then renders, then often a physical prototype you can hold.
- Manufacture: the piece gets made, either by hand or cast, with stones set and metal shaped.
- Finishing: polishing, plating, engraving and hallmarking happen here, right before the piece lands in your hands.
Each stage nudges the cost and the clock. More revisions at the design stage mean more time before metal gets touched. Hand fabrication generally costs more than casting but gives you finer control over the final shape. The sign-off moments that matter most are the design approval (once you’ve seen CAD or a prototype) and the final quality check before collection, both of which the National Association of Jewellers recommends recording in writing to keep everyone honest.
Preparing for your first consultation and briefing
Turn up with something to show, not just an idea in your head. Jewellers can work from a vague description, but they work better, and faster, with references.
- Visual references: photos from Pinterest, Instagram or old family jewellery you admire.
- Existing stones or metal: a grandmother’s ring, loose diamonds, anything you want reused.
- A budget band: not a precise figure necessarily, but a range you’re comfortable naming.
- The story behind the piece: an engagement, an anniversary, a memorial. It shapes design choices more than you’d think.
Most jewellers offer this first chat free of charge. It’s a scoping session, not a sales pitch: the jeweller is working out what’s realistic for your budget and timeframe, not trying to upsell you into a bigger stone.
Ask what’s included in the price, how many revisions you get, and what happens if you change your mind halfway through. A decent jeweller will write your brief down there and then, not rely on memory.
Pro Tip: Bring a rough sketch even if you can’t draw. A stick figure with notes beats a verbal description every time.
Turning your idea into a design: sketches, CAD and prototypes
This is where your idea stops being a feeling and starts being a file. Most jewellers begin with a hand sketch, quick and rough, just to agree on shape and proportion before anyone touches software.
From there it goes digital. CAD (computer-aided design) lets the jeweller model the piece precisely, adjust proportions in minutes, and generate a photorealistic render so you can see metal colour, stone placement and scale before a gram of gold gets cut. Some jewellers go a step further and 3D print a resin prototype, a physical mock-up you can actually try on. It won’t feel like the finished piece, but it tells you far more than a screen ever could.
- Hand sketches: fast, cheap, good for agreeing on overall shape.
- CAD renders: precise, let you check proportions and stone placement digitally.
- Resin prototypes: physical, let you check fit, comfort and scale on your hand.
Expect two or three revision rounds as standard before anyone casts or carves anything. Check setting heights (will the stone catch on jumpers?), band width (will it sit comfortably against other rings?) and overall proportion against your hand or body. Sign off each version in writing, even if it’s just an email saying “yes, this one”. That record protects you and the jeweller equally if a dispute ever arises later.
How a bespoke piece actually gets made
Here’s where the metal starts to matter. Jewellers broadly take one of two routes, and each comes with trade-offs worth knowing before you pick one.
Hand fabrication, forging and soldering sheet or wire metal into shape, gives a jeweller total control and tends to produce a slightly denser, more refined piece, though it costs more in skilled labour hours. Lost-wax casting, where a wax or 3D-printed model is used to create a mould that molten metal is poured into, is faster and cheaper for complex shapes, and it’s the route most commercial bespoke rings actually take.
- Hand fabrication: slower, pricier, favoured for simple bands and pieces needing structural strength.
- Lost-wax casting: faster, more affordable, well-suited to intricate or sculptural designs.
- 3D-assisted casting: combines CAD precision with casting speed, now common for complex bespoke commissions.
Stone setting choices (claw, bezel, pavé, channel) affect both how secure a stone is day to day and which stones can be used at all: a thin claw setting, for instance, isn’t ideal for a soft stone like opal. Finishing then covers polishing to the final shine, plating (rhodium on white gold, for example) and any engraving, followed by a final quality check against the original brief before the piece goes anywhere near a customer.
What the UK hallmark actually guarantees
Hallmarking isn’t decoration, it’s the law. Any qualifying item of gold, silver, platinum or palladium sold in the UK over a minimum weight threshold must carry a hallmark, as set out in GOV.UK’s hallmarking guidance. A full hallmark includes a sponsor’s mark identifying the maker, a millesimal fineness mark stating purity, and the assay office mark itself, independently verifying metal content rather than just taking the seller’s word for it. Dealers must also display a Dealers’ Notice explaining this to customers. Assay normally happens once the piece is finished, right before it reaches you.
What a bespoke piece typically costs and how long it takes
Simple remodels, resetting a stone into a new band, say, can take a couple of weeks. A standard bespoke engagement ring usually runs longer once you factor in design rounds and casting time. Anything with multiple stones, intricate engraving or an unusual setting stretches further still, simply because there’s more to get right at every stage.
Cost is driven mainly by metal weight, design complexity, the stones involved, and how many revision rounds you use. Rush orders cost more because they skip the queue, and queues exist for a reason.
- Deposits: most jewellers ask for a percentage upfront before design work begins.
- Staged payments: larger commissions often split payment across design approval and collection.
- Changes policy: ask upfront what happens, cost-wise, if you change your mind after casting has started.
Always get the deposit and changes policy in writing before anything gets made.
How a trustworthy jeweller documents bespoke work
A reputable bespoke jeweller doesn’t just make the thing, they can show you how. A reputable bespoke jeweller is often family-run, with many years of trading and in-house workmanship, meaning the people designing your piece are often the same people cutting and setting it, not a third party down the supply chain.
Every finished piece should carry proper hallmarking and authentication as standard, not as an optional extra. For readers who want to see the stages play out on a real commission, Blackwell’s own posts on how bespoke jewellery design works and the journey from sketch to finished piece walk through it in more depth. Always ask for written approvals and terms at every milestone, not just at the end.
A maker’s take on managing risk and expectations
Here’s the thing nobody tells you upfront: the biggest risk in bespoke jewellery isn’t the design, it’s the silence between approvals. Staged sign-offs protect both sides because they turn “I thought you meant” into a paper trail. A CAD render always looks a touch different from hand-finished metal, so go in expecting a little compromise, and talk about it before you’re disappointed by it.

FAQ
What is the 2:1:1 rule in jewellery?
There’s no single recognised “2:1:1 rule” documented in official jewellery trade guidance, and definitions circulating online vary widely. Rather than relying on an unverified shortcut, ask your jeweller directly how they scale stone and band proportions for your specific design.
What are the steps involved in making custom jewellery?
The process runs through consultation, design development (sketches, CAD and often a prototype), manufacture by hand fabrication or casting, and finishing, which includes polishing and hallmarking. You approve the design at key points before any metal is cut, as the NAJ’s guidance recommends.
What does “bespoke” mean in jewellery?
Bespoke means a piece designed and made specifically for one client, built from scratch around their brief rather than adjusted from an existing design. It typically involves direct collaboration with a jeweller through sketches, CAD and prototyping before manufacture begins.
How much does a bespoke engagement ring cost?
Cost depends on metal weight, design complexity, gemstones chosen and how many revision rounds you use, so there’s no fixed figure. Bespoke jewellery pricing is typically not published online; jewellers provide quotes based on specific briefs during consultation.
