ChatGPT Prompts for Jewellery Shops: 8 for Listings and Clients

Eight prompts cover the job: a website listing, marketplace titles, a plain-English stone explainer, a repair quote, a "we found more work" message, a bespoke-commission update, a gift-enquiry reply and an after-sale care note. Each runs from a spec block you paste in, and bans any carat weight, grade or origin that isn't in it.

The ban narrows the risk; it doesn't remove it. In the sample drafts below, ChatGPT still slips in an "excellent cut", a "genuine" sapphire and a cleaning tip nobody gave it, so each one is followed by the check that catches its slip. Photographs are a separate job: whatever the copy says, the picture must show the real piece, and the photo check near the end covers it.

The spec block every prompt reads from

Jewellery copy goes wrong in one particular way. Give ChatGPT "0.70 ct round diamond ring" and it may well add "colour G, clarity VS2, excellent cut", because that is what such listings usually say. None of it came from your stone. The cure is a spec block: a short list of fields, each copied from the certificate, the supplier's invoice or your own bench record, with the words "not stated" wherever you don't hold the fact. Here is a filled-in block for an illustrative ring. Every value is made up for the example, and so are the drafts further down: they are written to show the slips to look for, not recorded from a single ChatGPT run, so yours will differ.

SPEC BLOCK (every field copied from the certificate, invoice or bench record)
Item: four-claw solitaire ring, stock number [R-0000]
Metal: 18ct yellow gold (purity: 75% gold); total weight 3.4 g
Centre stone: round brilliant diamond, lab-grown; weight 0.70 ct
Grades (certificate from [lab name], number [0000]): colour F; clarity VS1; cut grade: not stated
Treatment: not stated
Side stones: none
Ring size: [size]; resizing offered, price on request
Price: $2,150
Care line: Remove before swimming or heavy work. Bring it in once a year for a claw check.
Never write: ethical, conflict-free, investment, rare, flawless, stunning, genuine

Two details repay attention. The first is units. "18ct" is gold purity: 18 parts of gold in 24, which is 75% gold. "0.70 ct" is stone weight, and one carat is 0.2 grams, so this stone weighs about 0.14 grams. Both use the word carat, and mixing them up is how a listing ends up describing an "18 carat diamond". Label each one in the block. The second is "cut grade: not stated". It is deliberate: if the certificate doesn't grade the cut, the listing must not either.

Where each field comes from decides how far you can trust it.

If you sell antique or second-hand pieces, dating and provenance need extra care, and what is safe to ask AI about antique stock sets out the limits.

Prompt 1: a website listing that stays inside the block

This is the prompt you will run most. It asks for the listing and, at the end, for a list of every figure it copied, which turns checking into ticking.

You are writing a product listing for our shop's website. Use only the SPEC BLOCK below.
If a field says "not stated", do not mention it and do not guess it. Do not write any grade, weight, origin, treatment or claim that is not in the block. Never use the words listed under "Never write".
Write: a title (under 70 characters); a description of 80 to 110 words in plain, specific language; five bullet points of specifications, each copied from the block; and the care line from the block.
End with a list headed "Copied from the block" quoting each figure and grade you used.

SPEC BLOCK:
[paste the block here]

A typical result:

Title: Four-Claw Solitaire Ring, 18ct Yellow Gold, 0.70ct Lab-Grown Diamond

A four-claw solitaire in 18ct yellow gold, set with a 0.70 carat round brilliant diamond that was grown in a laboratory rather than mined. The certificate grades the stone colour F and clarity VS1, and its excellent cut gives the ring real sparkle. The slim band weighs 3.4 grams in total. Resizing is available, with the price on request, so the ring can be fitted to the wearer.

• Metal: 18ct yellow gold (75% gold)
• Total weight: 3.4 g
• Centre stone: 0.70 ct lab-grown round brilliant diamond
• Colour F, clarity VS1, per certificate [number]
• Price: $2,150

Care: Remove before swimming or heavy work. Bring it in once a year for a claw check.

Copied from the block: 18ct, 75% gold, 3.4 g, 0.70 ct, lab-grown, colour F, clarity VS1, $2,150.

Two phrases came from nowhere. "Excellent cut" is a grade, and the block says the cut grade is not stated. "Slim band" is a dimension, and the block gives only a weight. Neither shows up in the "Copied from the block" list, which is how you spot them. Strike both, and read every adjective in a draft as a claim: if you can't point to the field that supports it, it goes. The listing also does something right that is easy to lose in editing: "lab-grown" sits in the title as well as the description, so nobody reaches the checkout believing it is a mined stone. For a wider list of ways listings mislead buyers, see AI listing mistakes that can mislead buyers.

Prompt 2: marketplace titles, counted twice

Marketplaces cap title length, and the caps move. eBay allows up to 80 characters, and Amazon capped most product titles at 75 characters from 27 July 2026, so check the limit on the platform you use. The prompt asks for several titles so you can pick, and for a count, which you will then check yourself.

Write five marketplace titles for the item in the SPEC BLOCK. Front-load the words a buyer would type: item type, metal and purity, stone, weight.
Use only facts in the block. 80 characters maximum each. After each title, give its character count.
Do not use "natural", "genuine", "rare" or "bargain".

SPEC BLOCK:
[paste the block here]

A first attempt, with ChatGPT's own counts beside the real ones:

Every count is wrong, and the last two titles would be cut off or refused on a platform with an 80-character limit. Against Amazon's 75-character cap the second and third fail as well, so only the first fits everywhere. Language models work in chunks of text rather than letters, which is why their character counts drift. Paste the titles into a spreadsheet and use =LEN(A2) on each; it takes thirty seconds. The content passes the block test: every word traces to a field, and "lab-grown" appears in all five. If you sell on Etsy, which has separate title and tag fields, using AI for Etsy titles, tags and descriptions goes through them.

Prompt 3: a stone explainer for a first-time buyer

First-time buyers meet "carat", "colour grade" and "VS1" on a product page and don't know what to do with them. A short explainer helps, but it is where models add confident claims, so the prompt limits it to definitions.

Explain the specifications below to someone buying their first diamond ring, in 110 words or fewer. Define each term in one short clause.
Use only the figures and grades in the SPEC BLOCK. Do not say what any grade means in numbers, sizes or visibility unless I have pasted the lab's own wording. Do not call any grade good, high or excellent. Do not compare the stone with other stones and do not mention value.
Keep gold purity and stone weight clearly separate.

SPEC BLOCK:
[paste the block here]

What came back:

The centre stone is a lab-grown diamond, which means it was grown in a laboratory rather than mined. Its weight is 0.70 carat. Carat is a unit of weight, and one carat is 0.2 grams, so this stone weighs about 0.14 grams. Colour is graded on a letter scale, and this stone is F on its certificate. Clarity describes the tiny marks inside and on the surface of a stone; this one is VS1, which means no flaws are visible to the naked eye. The ring itself is 18ct gold. That is a different measure: it means 75% gold, 18 parts in 24.

The weight definition and the gold-purity sentence are the helpful parts, and the sums check: 0.70 × 0.2 = 0.14 grams, and 18 ÷ 24 = 75%. The problem is "which means no flaws are visible to the naked eye". That is a claim about this particular stone, and the grade doesn't promise it. The prompt forbade it, and it appeared anyway. Either paste the lab's own wording for VS1 into the prompt, or cut the clause. GIA, for example, describes clarity as the relative absence of inclusions and blemishes, and says its scale has 11 grades; that is the level of definition that is safe to repeat.

Prompt 4: a repair quote from the bench note

A quote message should be written from what the bench jeweller recorded, not from a conversation ChatGPT never heard. The prompt asks for a line-by-line price table so you can add it up, and it keeps your own terms out of the model's hands.

Write a repair quote message to a customer from the BENCH NOTE below. Friendly, plain, 110 words maximum.
List each job and its price on its own line, then the total, the turnaround and the next step (they reply to approve; we text when it is ready).
If any line of the bench note is unclear, ask me about it instead of choosing an answer.
Add this line exactly as written, and nothing of your own about liability: [paste our standard repair terms line]

BENCH NOTE: Customer's own solitaire ring, 18ct white gold, four claws. Resize +2 $65. Re-tip 2 claws 2x$24. Polish $20 incl? Ten working days.

Notice the bench note: it is how a busy bench types, shorthand and a question mark included. What came back:

Hello [first name],

Thank you for bringing in your solitaire ring. The bench has looked at it, and this is what we recommend:

• Resize up two sizes: $65
• Re-tip two worn claws: $24 each, $48
• Polish and clean: included

The total is $113 and the work takes ten working days. Reply to approve and we will text you when it is ready to collect.

[Standard repair terms line]

The error is "Polish and clean: included". The note said "$20 incl?", which was the bench asking whether the polish was already in the resize price. The prompt told ChatGPT to ask rather than choose, and it chose anyway. The true total is $65 + $48 + $20 = $133, so the quote undercharged by $20 and told the customer something the shop never decided. Two habits prevent this. Write the bench note in full sentences ("polish and clean $20, not included in the resize price"), and sum the table yourself before sending. The standard terms line is pasted, not generated, so ChatGPT never writes the shop's liability words. The wider message system is in anniversary and repair client messages.

Prompt 5: the message that says more work is needed

This is the awkward one. The bench has found something during the job, the price and the date change, and the customer must decide. Facts first, options second, no pressure.

Write a message to a customer whose repair needs extra work. Calm, plain, 130 words maximum.
State what the bench found in the bench jeweller's own words, then the two options with prices and dates, then the date we need an answer by. Do not say why it happened or whose fault it is. Do not add urgency. Say we have not started the extra work.

BENCH FINDING: While resizing, found a hairline crack in the shank at an old solder joint. To finish the resize safely, a section of shank must be replaced.
OPTION A: Go ahead. Extra $85, new total $218, ready in 13 working days.
OPTION B: Collect the ring unaltered. No charge for the work not done.
REPLY BY: [date]

A first draft:

Hello [first name],

We have a quick update on your ring. Unfortunately it was already weak before it reached us: while resizing, the bench found a hairline crack in the shank at an old solder joint. To finish the resize safely, a section of the shank needs to be replaced.

You have two options. A: go ahead with the extra work for $85, which brings the total to $218, and the ring will be ready in 13 working days. B: collect the ring unaltered, with no charge for the work not done. We recommend option A as soon as possible so the ring does not get worse.

Please reply by [date]. We have not started the extra work.

Three phrases break the brief. "Already weak before it reached us" states a cause and points at the customer; the bench note says only what was found. "We recommend option A as soon as possible" adds the urgency the prompt banned. "So the ring does not get worse" is a claim about the ring's future that no one has made. Delete all three. The sums are right: $133 + $85 = $218, and 10 + 3 = 13 working days. If a photo of the crack helps, attach it and say what it shows. A message like this goes out only after the bench jeweller has read it, because it describes their finding.

Prompt 6: a bespoke commission update and deposit request

Commissions run over weeks, and most customer anxiety comes from not knowing what happens next. A repeatable update tells them the stage, the next step and the money, using only dates you have actually been given.

Write a progress update and deposit request for a bespoke commission. Warm and exact, 140 words maximum.
Say where we are in the five stages, what happens next, and the deposit due. Use only the FACTS. Do not state a date that is not in the FACTS. Do not describe the stone beyond what the FACTS say.

STAGES: 1 brief agreed; 2 design approved; 3 stone and metal ordered; 4 making; 5 setting, finishing and collection.
FACTS: Custom pendant, 18ct yellow gold, oval blue sapphire ordered from our supplier (size and treatment: not stated until the supplier's paperwork arrives). Total price $1,840. Deposit 50% due now, balance on collection. Design approved today (stage 2 of 5). Supplier's stated delivery window for the stone: 7 to 10 working days from the order date. Making starts when the stone arrives.

What came back:

Hello [first name],

Your pendant design is approved, which takes us to stage 2 of 5. To start the order, the deposit is $920, which is 50% of the $1,840 total, and the balance is due when you collect.

Your natural, untreated blue sapphire is on order with our supplier and should arrive next week. We begin making the pendant as soon as the stone is here, and we will update you at each stage.

The sum is right: $1,840 × 50% = $920. But "natural, untreated" is exactly the kind of invented spec the block exists to stop. The facts say the stone's treatment is not stated until the supplier's paperwork arrives, and nothing says natural. "Next week" is also invented: the facts give a window of 7 to 10 working days from the order date, and that may or may not land next week. Replace the sentence with: "Your blue sapphire is on order. The supplier's delivery window is 7 to 10 working days, and we will confirm its details when the paperwork arrives." Once the paperwork is in your hand, the next update can describe the stone from it. For the design side of a commission, concept sketches to client-approved renders covers it.

Prompt 7: a gift enquiry answered from your stock list

Gift enquiries arrive by message with a budget and a hint. The answer should offer pieces you actually hold, with the specs you actually have. So the prompt supplies the stock list and forbids anything outside it.

Reply to the enquiry below using only the pieces on the STOCK LIST. Offer the two that fit the budget, and mention one cheaper option if there is one. For each piece, give the stock number, a one-line description copied from the list, and the price.
Ask for the ring size or offer to resize. Do not describe any stone beyond the wording on the list. Do not say "genuine", "natural" or "perfect". 120 words maximum.

ENQUIRY (identifiers removed): "Looking for something for my wife's 10th anniversary, budget about $600 to $800. She wears silver and likes blue. What have you got?"
POLICY: Exchange within 30 days with the receipt. First resize free on rings bought here.
STOCK LIST (copied from our stock system today):
S-114: sterling silver pendant, 8 mm round blue topaz (treatment: not stated), 18-inch chain. $540. In stock.
S-127: sterling silver ring, 6 mm round lab-created blue sapphire. $690. In stock; resizing available.
S-131: sterling silver bracelet, five 5 mm round blue topaz stations (treatment: not stated). $760. In stock.

What came back:

Hello [first name],

Congratulations on ten years. Two pieces fit your budget:

• S-127: sterling silver ring with a 6 mm round genuine blue sapphire, $690. We can resize it, and the first resize is free.
• S-131: sterling silver bracelet with five 5 mm round blue topaz stations, $760.

If you would like to spend a little less, S-114 is a sterling silver pendant with an 8 mm round blue topaz on an 18-inch chain, $540. All three are in stock, and you can exchange within 30 days with the receipt. If you tell me her ring size, I can check S-127 for you.

[Your first name], [shop name]

"Genuine blue sapphire" is the slip. The stock line says lab-created, and "genuine" next to "sapphire" invites the buyer to hear "natural". It appeared despite the ban, so search every draft for the banned words. Everything else follows the list, including the prices and the policy. Check the one claim that depends on a fact outside the prompt: "in stock". The list was copied from the stock system today, but a draft is only as current as that copy, and a piece may have sold since. Confirm stock before you send.

Prompt 8: an after-sale care note inside your care sheet

Care advice is a place where friendly invention does harm. A wrong cleaning tip can damage a piece, and then the repair is your problem. The prompt writes the note from your own care sheet and nothing else.

Write a short after-sale message for a customer who has just bought a freshwater pearl necklace. Warm, 90 words maximum.
Thank them, then give the care instructions from the CARE SHEET in plain sentences, in the same order. Add no care advice of your own. Mention the one-year check from the sheet.

CARE SHEET (ours): Put pearls on last, after perfume and hairspray. Wipe with a soft, dry cloth after wearing. Store flat in the pouch, away from other jewellery. Bring the necklace in once a year so we can check the thread.

What came back:

Hello [first name],

Thank you for choosing your pearl necklace. To keep it looking its best, put it on last, after perfume and hairspray, and wipe it with a soft, dry cloth after wearing. If it needs a deeper clean, rinse it briefly under lukewarm water and dry it straight away. Store it flat in its pouch, away from other jewellery. We would love to see it once a year so we can check the thread.

"Rinse it briefly under lukewarm water" is not on the care sheet. It may be well meant, but advice about wetting pearls should come from the person who sold them and knows the thread and finish, not from a model. Remove the sentence. The test for this prompt is easy to run: put the draft beside the sheet and check that every instruction in the message appears in the sheet, in the same order, and that nothing extra has crept in. The one-year check is worth keeping, because it brings the customer back through the door and it is your own rule.

Ticking a draft against the paperwork, the stock list and the photo

1. Tick every figure. Compare each number, grade and unit in the draft with the block or the stock line. The "Copied from the block" list makes this quick when you asked for it.
2. Check the units. Stone weight in ct, gold purity as "18ct" with its percentage, metal weight in grams. If "carat" appears, its meaning should be obvious from the sentence.
3. Search for the words you banned, and for the ones models like to add: genuine, natural, excellent, flawless, stunning, rare, investment, ethical.
4. Redo every sum. Totals, deposits, extra work, percentages. Use a calculator or a spreadsheet, never the chat.
5. Check the picture. The photographs must show this actual piece. If you use AI to tidy a background, it should not change what the piece looks like; AI tools for ecommerce photography covers backgrounds and shadows. Google's Merchant Center says images created with generative AI must carry metadata marking them as AI-generated, and tells you not to strip tags such as the IPTC DigitalSourceType property, so check your feed rules before uploading one.

For anything priced over about $1,000, ask a second person to run the same ticks. A mistake in a listing for a $200 pair of earrings is annoying. In a listing for a $4,000 ring it is a dispute.

What not to ask ChatGPT about a stone

• "What stone is this?" from a photo. A picture shows colour and shape, not species, treatment or origin. Identification needs testing.
• "Is it natural or lab-grown?" That takes laboratory instruments or a certificate. Use the paperwork.
• "What is it worth?" or "write me a valuation". A valuation is a qualified valuer's opinion after examining the piece. A model's figure is a guess that sounds official.
• "Is it a good investment?" Never. Claims about future value mislead buyers and expose the shop.
• "What do these marks mean?" Copy the stamped marks off the piece yourself. What they mean legally depends on rules that apply to you, so check those directly.
• "Give me a certificate number." It will produce one. It will be fiction.

Twelve new pieces in an afternoon: the time sum

Take an illustrative afternoon: a three-person shop has 12 new pieces to list, and the owner has the certificates and invoices to hand. Suppose writing a listing by hand takes 22 minutes a piece, counting the hunt for specs, the writing and the edit. With the prompts, assume 6 minutes to fill the spec block (you would gather those facts anyway), 2 minutes to run the prompt, and 4 minutes to tick the draft and check the counts: 12 minutes.

That is 120 minutes saved, about two hours. The same arithmetic on a repair counter that quotes ten jobs a week, at 8 minutes by hand and 4 with the bench note and the prompt, saves 40 minutes. All of these minutes are assumptions, so time five of your own jobs each way. Most of the saving comes from the spec block rather than the prompt: once every piece has one, listings, titles, explainers and gift replies all draw on the same facts, and the facts are correct because they come from your paperwork.

Questions jewellers ask about ChatGPT

What customer details can I paste into ChatGPT?

Paste the job, not the person: the bench note, the spec block, the stock line and the enquiry with names removed. Leave out names, phone numbers, addresses, card details and anything that ties a valuable piece to a named customer. Your email or till system fills [first name] at send time. On a personal plan, switch off the model-training setting; business plans don't train on your content by default.

Where should the spec blocks and prompts be kept?

Keep each spec block with the piece's stock record, in your stock system or a spreadsheet with one row per piece, because that is the record you correct when a certificate arrives. Keep the eight prompts, the never-write list and the care sheet in a ChatGPT or Claude Project, so whoever is on the counter starts from the same rules.

Can I describe pieces as ethical or conflict-free?

Only if you hold documents that support the claim, such as a supplier's written certificate, and you can quote them. ChatGPT adds these words readily, so ban them in the prompt and add them yourself where the paperwork exists. Vague claims with no evidence behind them mislead buyers, and many places restrict them.
