Write the brief into fixed fields (occasion, budget, metal, stone, setting, wear), turn the design fields into clauses of an image prompt, generate eight to twelve variants and show the client three, labelled as concepts. When they choose one, redraw it in CAD before quoting: a render shows an idea, not a makeable piece.
An image generator starts from words, not from your client's stone, budget and lifestyle, so the brief has to carry those. It also draws without knowing how metal is cast or stones are set. Renders often show claws (prongs) too thin to hold the stone, bands that cannot be sized and designs that echo someone else's. Your eye, not the generator, has to catch those before the client sees them.
Ten brief fields a prompt can actually use
A conversation with a client produces feelings; a generator needs facts. Capture the brief in the same ten fields every time, on a short form the client completes or that you fill in during the consultation. Fields three to nine turn straight into prompt clauses (the no list becomes things to avoid). Fields one, two and ten decide what is feasible and what you may use as reference.
- Occasion and deadline. An anniversary in eleven weeks changes what is realistic.
- Budget for the finished piece, stones included, and whether the client supplies the stone.
- Piece and placement: ring, pendant, earrings, and which hand or ear.
- Metal and finish, with any allergy noted.
- Stone or stones: type, shape, size in millimetres, colour.
- Setting style in the client's own words, plus how it should feel on the hand.
- Daily wear: hands-on work, sport, stacking beside other rings.
- Meaning: a motif, birthstone or engraving that must be present.
- The no list: shapes, styles or details to avoid.
- Reference material: the client's saved images or photos of an heirloom, with permission to use them.
Here is a completed brief for the sapphire ring commission worked through below. It is an illustration, not a real client.
| Field | Entry |
|---|---|
| Occasion, deadline | Tenth anniversary, eleven weeks away |
| Budget | $2,800 to $3,500; the client supplies the stone |
| Piece | Ring for the right hand; size to be taken from a ring she already wears |
| Metal | Yellow gold, polished; no nickel |
| Stone | Oval blue sapphire, about 8 by 6 mm, her own |
| Setting | Low and snug, nothing that catches; she wants to forget she is wearing it |
| Daily wear | Works with her hands at a potter's wheel; sits beside a plain wedding band |
| Meaning | A small leaf motif, because of where they met |
| The no list | Halos, anything ornate, sharp edges |
| References | Three images she saved, plus a photo of her grandmother's ring, which she owns |
Notice how much of this a generator could never guess: the potter's wheel is the reason for the low setting, and the wedding band is the reason the shoulders must sit flat. A prompt built only from "sapphire anniversary ring" would have produced something pretty and wrong. If a client brings a photo of a piece made by another designer and asks for something like it, treat the photo as a conversation about what they like (the proportions, the colour, the story) and do not upload it as a base. More on that further down.
From brief to prompt: one clause per decision
Write the prompt in the order a jeweller describes a piece: what it is, the metal, the stone, how the stone is held, the style, then how to photograph it. Short, concrete clauses beat adjectives. Compare a vague prompt with a specific one built from the brief above.
Vague
beautiful vintage sapphire ring, elegant, luxury, sparkling
Specific
Ring. Yellow gold band 2.5 mm wide, gently tapered, high polish. Low bezel
setting around an oval blue sapphire 8 x 6 mm. A tiny engraved leaf beside
the stone. Flat, low shoulders. Studio product photograph, three-quarter
view, pale grey background, soft shadow, realistic scale for an adult finger.The vague prompt hands every decision to the generator, and you are likely to get the generator's idea of luxury: a halo, pavé shoulders and sparkle that belong to someone else's brief. The specific prompt names the structure (bezel, flat shoulders, low profile), which is exactly what the client said she needs. Generators do not measure, so treat "8 x 6 mm" as a request and check the proportions yourself later. A style word such as "vintage" is worth a clause only if you can say what you mean by it, such as "milgrain edge detail".
You do not have to write every prompt by hand. Give the brief to a text assistant and ask for a set of prompts that differ on one decision each. This keeps the variants comparable, and the client can see what each choice changes.
Here is a client brief for a bespoke ring. Write four image prompts. Each
has one deliberate difference: (1) bezel setting, (2) low four-claw
basket, (3) flush setting with the stone sunk into the band, (4) partial
bezel with open sides. Keep everything else identical. Describe construction
in plain words a jeweller would use. Do not mention any designer, brand or
collection. End each prompt with: studio product photograph, three-quarter
view, pale grey background, realistic scale for an adult finger.
[paste the ten-field brief, without the client's name or address]Strip the client's name, address and any dates of birth before pasting. The generators and assistants do not need them, and the brief often holds more personal detail than the design needs.
If you can draw, there is a stronger route. Make a quick pencil sketch of the idea, photograph it and use it as the starting image, asking the tool to render your sketch instead of inventing a design. Most generators accept an uploaded image as a starting point; check that yours does before you plan around it. The result is more likely to be yours in every sense: the structure comes from your hand, and the generator supplies surface, light and polish. A sketch with a few dimension notes also gives the CAD designer a head start.
Three rounds, changing one thing at a time
Clients choose better when the options differ in one obvious way. Run the images in rounds, and in each round change one family of decisions while holding the rest fixed.
| Round | What changes | What stays fixed | Images | You keep |
|---|---|---|---|---|
| 1. Families | Setting style (four options), and metal tone for the two best | Stone, budget, band width, camera view | 12 | 3 to show the client |
| 2. Refinement | Details inside the chosen family: band profile, leaf position, shoulder shape | Everything the client approved in round 1 | 6 | 1 |
| 3. Hand-off | Nothing new: top and side views of the chosen design | The round-2 image | 2 | 1 sheet for CAD |
Before any image reaches the client, cull it yourself. Drop an image if the stone is the wrong shape or colour, if the number of claws or the wall of a bezel looks too slight for the stone, if the band changes width without a reason, if one side of a symmetrical piece differs from the other, or if it looks uncomfortably like something you have seen in a shop window. The cull is quick, because you know what a makeable ring looks like, and it is the step that stops the client falling for an image you would have to disappoint them over.
A good assistant can speed the cull without replacing your eye. Upload the render and ask it to describe the construction as a jeweller would: how the stone is held, what the visible metal thickness is, what looks uncastable. Treat the answer as a second pair of eyes, not an inspection. It will sometimes call a hidden feature secure because it cannot see it, and it will miss faults a loupe would find.
Here is the kind of reply to expect, and what to do with it (illustrative). Asked how the stone is held in a round-1 image of the partial bezel, an assistant might answer:
The sapphire sits in a bezel wall that follows the oval outline and appears even, about as thick as the edge of the band. Two short gaps on the long sides look like the open sections. I cannot see the underside, so I cannot tell whether the stone has a seat.
Three things are worth taking from that. "Appears even" is a judgement from one angle and proves nothing about wall thickness. The last sentence is the honest one: the underside is unseen, which tells you to ask for a rear view before this image goes near a client. And "two short gaps" shows the generator did produce an open-sided bezel, a point in the image's favour. Nothing in the reply replaces measuring in CAD.
A worked commission: the sapphire ring from brief to approval
The figures below are illustrative, but the sequence is the real one. The brief is the table above.
Intake and prompts (45 minutes). Thirty minutes on the form and a call, then fifteen turning the brief into four prompts with an assistant and editing them. The four settings were bezel, low four-claw, flush and partial bezel.
Round 1 (40 minutes). Twelve images, three per prompt, in about twenty-five minutes including reruns, then fifteen minutes culling. Five were dropped: two had claws that plainly could not hold an oval, one had a band that swelled on one side, one turned the stone into a round, and one had a shoulder detail that closely resembled a well-known branded design, which a reverse image search then confirmed. Seven were left. Three went to the client as concepts A, B and C, chosen to be as different from each other as possible.
Client meeting (20 minutes). She chose B, the partial bezel, and asked for a narrower band with the shoulders sitting flat so her wedding band could butt against it.
Round 2 (25 minutes). Six images varying band width and shoulder shape, with the leaf placed on the side of the stone where it would not meet the wedding band. One image was chosen.
Hand-off (20 minutes). Two more views, then a dimension note for the CAD stage.
That is about two and a half hours of the jeweller's time and twenty images for one approved concept. The client sees three clearly different concepts at the first review, and the CAD designer starts from a picture the client already loves and a sheet of constraints that explains why it looks the way it does.
Cost per image, and cost per approved concept
As of October 2026 the main options price like this. The figures are list prices in USD from each vendor's own pages, and what the plans include changes often, so read the current page before you buy.
| Tool | List price a month | What its own page says about images | Worth knowing for client work |
|---|---|---|---|
| ChatGPT | Go $8, Plus $20, Pro from $100 | Image generation on every plan: limited on Free, more on Go, "more complex and accurate" on Plus, unlimited and faster on Pro | Takes a typed brief or an uploaded sketch, and can also describe a render's construction |
| Gemini | AI Plus $4.99, AI Pro $19.99 | Image generation and editing in the app on the free plan; paid plans raise usage limits to 2x and 4x the free ones | The free plan is enough to test the method on one commission |
| Midjourney | Basic $10, Standard $30, Pro $60 | Basic includes 3.3 hours of fast generation; Standard adds unlimited relaxed images | Your content is publicly viewable by default; private Stealth mode is only on Pro and Mega |
| Adobe Firefly | Standard $9.99, Pro $19.99 | Unlimited standard image generation on paid plans; partner models spend credits | Adobe says outputs of its own Firefly models are safe for commercial use; partner-model outputs are your call |
Per-image prices are hard to compare because each tool counts differently, and several do not publish an image limit at all. A more honest measure is the cost per approved concept. Count the images you generate in a typical month (every tool keeps a history). The plan price divided by that count is your cost per image, and the plan price divided by the month's commissions is your cost per approved concept. Say you take six commissions a month and make about twenty images for each, which is 120 images. On a $20 plan that is about $0.17 an image and $3.33 a commission. On a $60 plan, chosen for the private mode, it is $0.50 an image and $10 a commission. On a $9.99 plan it is about $0.08 and $1.67. Whether 120 images fit inside a plan's limits is something only a real month of use will tell you, so start on a free tier or a one-month plan.
The tool is the cheap part. The sapphire ring took about two and a half hours of your time, and CAD is a skilled step in its own right, and dedicated jewellery CAD software such as Gemvision's MatrixGold is a substantial purchase (its store shows prices by country, so check the current licence cost there), which is one reason a small studio may send the chosen concept to a CAD designer or bureau instead. What the renders buy you is a faster, better-informed decision before that money is spent. For a closer look at what a usable image costs after the rejects, see Midjourney pricing per image, and to price the finished piece use a jewellery pricing calculator for metal, labour and markup.
What a render cannot tell you
A render is a picture of a plausible object. Nobody has tested it against metal, gravity or a finger. This table lists what each part of an image shows, what it can hide and how to check.
| What the image shows | What it can hide | How to check |
|---|---|---|
| A stone of about the right size | Real proportions: generators do not measure | Draw the stone to scale (8 by 6 mm here) over the render and compare it with the band width |
| A setting that looks secure | Claws too thin or too few, or a bezel with no seat for the stone | Hold it against your own minimum thickness for that metal and the stone's weight |
| A comfortable-looking band | Uneven width, no room to resize, a thin spot underneath | Draw the cross-section and allow for sizing |
| One flattering view | The underside, the gallery and how the parts join | Ask for rear and side views; if the generator cannot produce a consistent one, the design is not resolved |
| A symmetrical pair of earrings | Small differences between left and right | Mirror one half over the other |
| A warm yellow or a cool white metal | Lighting and reflections, not real alloy colour | Compare with your sample alloys in daylight |
| Nothing about weight | The grams in the piece, and so the metal cost | Take the weight from the CAD model's volume, then price it |
The commonest failure is a structure the image makes look natural. Suppose a client falls for a ring whose halo floats around the stone with no visible connection. In CAD the halo needs bridges or a gallery, and the look the client loved changes. The jeweller then absorbs a redesign or a disappointed customer. The remedy lies upstream: cull any image whose structure you cannot explain in a sentence, and put "concept, not engineering drawing" on every image you show.
The hand-off to CAD then has five parts: the chosen render with its side and top views; a dimension sheet with stone sizes and any minimums you work to; the client's finger size and how the ring will be worn; the constraints (here, flat shoulders beside a wedding band and no halo); and a note of what the render could not show. The CAD output, with real dimensions, is what you quote from, and it is what the client approves a second time. Keeping rings and chains true to scale shows how to test scale claims in images.
Keeping the design your own
Image generators learn from huge collections of pictures, and jewellery has famous signature designs. Four habits keep your work clearly yours.
- Keep names out. No designer, house or collection names in prompts, briefs or saved instructions. "In the style of" asks the tool to reproduce recognisable features.
- Seed from your own work. Start from your sketches, or from the client's own heirloom photographed with their permission. An heirloom is the client's piece; another designer's catalogue photo is not a base to build on.
- Search before the client sees. Run each concept through a reverse image search such as TinEye or Google Lens, and look for near-identical hits. If one appears, change the structure with a new idea, not just a new colour.
- Keep a provenance note. For each commission, store the brief, the prompt text, the tool and date, the image names and your sketches in one folder. If anyone ever asks how a design came about, you can show it.
If a client asks for a close copy of a branded piece, steer them to what they like about it and design something distinct. Copying a protected design can expose you, and an intellectual-property adviser is the right person to ask when you are unsure.
Ownership and privacy depend on the tool. Midjourney's terms say you own your assets to the fullest extent possible under applicable law, require its Pro or Mega plan for a company with more than $1,000,000 a year in revenue, and make content publicly viewable and remixable by default. Adobe states that outputs from its own Firefly models are safe for commercial use. The rules on protecting purely AI-made images are unsettled and differ between countries, so your own sketches and your CAD model are the work you can most clearly call yours: keep them in the file. Keep client names, birth dates and addresses out of every prompt. Whether you can legally use AI images in marketing goes deeper on the licensing side.
The concept sheet a client approves, and the second approval after CAD
Many bespoke clients arrive with a thread of saved photos and the instruction "simple but special". The concept sheet turns that into a decision. Make it one page with three concepts, lettered A to C, in the same view on the same background so the client compares designs rather than lighting. Under each, give the metal, the stone and its size, the approximate band width, an estimate range from your pricing calculator (an estimate, not a quote) and one line on what is different about it.
Put a footer on the page and never trim it:
These images are illustrative concepts, not technical drawings. Stone sizes, proportions and construction are confirmed in CAD, and a price is confirmed after the CAD design is approved.
Then ask for approval in writing, in words the client cannot misread. Here is a message you can adapt:
Subject: Concept approval, anniversary ring
Hi [first name],
Thank you for choosing concept B. I will develop it in CAD with a narrower
band and flat shoulders so that it sits beside your wedding band.
Please reply "Approved: concept B to CAD" to confirm. Details may change
as the design is engineered, and you will see CAD images to approve before
anything is made. A written quote follows that approval.
[your name]That message sets up two approvals. The first is the concept, before CAD time is spent. The second is the CAD images, before anything is printed, cast or set. Between them you have replaced a picture with dimensions, so the second approval is the one that fixes the design. Decide your own terms in advance and write them down: whether concept work is free, a deposit or a design fee credited against the commission, and what happens to changes requested after the CAD approval. An adviser can check the wording for your trade.
To see whether the routine works, track four numbers for your first five commissions: images generated per commission, rounds before approval, the share of approved concepts that survived CAD without a redesign, and the cost per approved concept. If the third number is low, your cull is too lenient or your hand-off is missing constraints. If the first is high, tighten the brief, because a prompt that has to be rerun forty times is usually a brief that is not finished.
Skip generation when it cannot help. A repair, a re-set of an heirloom stone into its old mounting or a resize starts from the object itself, so photograph it, measure it and work from that. AI concepts earn their place on new commissions where the client cannot yet say what they want and you cannot yet show them.
Questions jewellers ask about AI concept renders
Can I show AI renders to clients as the finished design?
Show them as concepts only. A render is an impression: it can hide impossible settings, wrong proportions and metal too thin to hold a stone. Label every image as illustrative, redraw the chosen design in CAD, and get a second approval on the CAD images before you quote or cast.
Do I own the images an AI generator makes?
Terms differ, and the law on purely AI-made images is unsettled and varies between countries. Midjourney's terms say you own your assets to the fullest extent the law allows, and require its Pro or Mega plan for companies over $1,000,000 a year in revenue. Ask an intellectual-property adviser before relying on any image as protectable.
Which AI image tool is best for jewellery concepts?
The one that lets you control the details you care about at a cost per approved concept you can live with. Run the same brief through two tools you can already use before buying another plan, and judge the results on claw count, stone shape and band width rather than on how pretty the picture is.
How do I avoid copying another designer by accident?
Keep designer and brand names out of prompts, start concepts from your own sketches, and run a reverse image search on each concept before the client sees it. Keep a note of the brief, the prompts and the tool for every commission, so you can show how the design was developed.
