How to vet a wholesale jewelry supplier — from the other side of the table
Most vetting checklists tell you what to ask. The harder, more useful question is what a supplier will actually let you verify — the karat stamp, the diamond certificate, the terms in writing. Here is how I would vet us.
Vet a wholesale jewelry supplier by what they'll let you verify, not by what they tell you. Ask for three things in writing: the karat stamp on the metal, the lab and certificate on the diamond, and the terms — deposit, returns, warranty — in one place. A real factory answers all three, fast.
the one test that beats every checklist
Most vetting guides hand you a list of questions. A list is only as good as your ability to check the answers, so the test that beats every checklist is narrower than a checklist: separate what a supplier claims from what a supplier will let you verify, and weight the second far more heavily.
Karat is a claim you can verify. Ask what the gold is and the honest reply is a number and a stamp, not an adjective — we work in solid gold, 10k, 14k, and 18k, and "premium" is not a karat. Check the stamp, check the invoice, and check that the two agree. A supplier who reaches for the adjective when you asked for the number has already told you something.
A diamond certificate is verifiable too, but read what it actually certifies. A certificate tells you the grade of the stone in front of you. It does not, on its own, prove how the finished piece was made or set. Natural diamonds should be GIA-certified, lab-grown should be IGI-certified, and the certificates should be available on request. "Certified" with no lab named is not a certificate. It is a word.
what to make them prove, in writing
The fastest way to vet a supplier is to ask narrow questions and watch whether the answer is specific, written, and the same the second time you ask it. Here is the short version of what I would make any supplier — us included — put in writing.
| what to ask | a straight answer | a dodge |
|---|---|---|
| What's the metal? | Solid gold, 10k / 14k / 18k, stamped | "Premium gold," or plating sold as solid |
| Who certifies the diamonds? | GIA for natural, IGI for lab-grown, on request | "Certified," no lab named |
| Are the lab-grown stones conflict-free? | Yes — lab-grown is conflict-free by construction | A blanket conflict-free claim on every stone |
| How is pricing built? | Per buyer, line sheets on request | A retail markup dressed as wholesale |
| What are the terms? | 50% deposit on first orders, Net-15 once established | Verbal, vague, different each time |
| What if a piece is defective? | Free repair for defects in our craftsmanship | Silence behind "all sales final" |
The straight answers share a pattern: every one is narrow, and each reads the same in writing as it does on a call. All sales are final with us — that is normal in made-to-order wholesale — but the warranty behind it is specific: free repairs for defects in our own craftsmanship, with no fixed term. Final sale paired with a real defect warranty is a position you can plan around. Final sale with nothing behind it is the line to question, which is exactly why the deposit, returns, and warranty all belong on a written policies page rather than in someone's memory.
who you're actually buying from
The cheapest vetting question almost nobody asks is how many hands sit between you and the bench. Every layer between a factory and your shelf is a margin someone keeps and a detail someone can blur. We cut those layers out — not after the fact, but by being the manufacturing side. The founders' family has worked Surat's benches for over four decades, and the business runs across three real locations: Toronto and New York for the buyer, Surat for the craft.
This matters for vetting because the closer a supplier sits to the bench, the more they can both tell you and prove. A certificate proves the stone. The bench proves the piece — every one of ours passes a five-point QC before it leaves the floor. Ask a reseller how a setting was built and you often get a shrug; ask the factory and you get the checkpoint. The order itself should read clearly end to end — sample, spec, deposit, production, ship — with no step skipped to make a quote look faster than the work allows.
vet by your situation
What you should stress-test depends on where you sit. The principle holds across the board; the pressure points move.
If you are trying a supplier for the first time, buy small before you buy deep. Most of our styles carry a minimum of one unit, a sample is paid and non-creditable, and a first order runs on a 50% deposit — so the real cost of vetting us is a single piece in your hand. Hold it, weigh it, and check the stamp against the invoice. That one piece tells you more than any line sheet will.
If you are an established retailer scaling a program, vet the terms and the customization, not just the product. Net-15 is available once an account is established, volume pricing is quoted per buyer rather than posted, and a real factory can make to your spec — metal, stone, finish, packaging — or produce a design under your own label. A reseller cannot do that. A factory can.
If you are importing across a border, settle the logistics in writing before the first box ships. North American orders should be insured, signature-on-delivery, and land inside a known window; international moves on DAP terms, which means the duties and taxes are yours rather than a surprise at customs. A supplier who states that plainly is far easier to plan around than one who lets you find out on arrival.
Across all three situations the test is the one you started with. Weigh the claims you can check — the stamp, the certificate, the written term — and discount the ones you can't. The supplier worth keeping is the one whose answers don't change when you write them down.
Asked at the counter
Questions retailers ask
- What documents should a wholesale jewelry supplier provide before I order?
- At a minimum, the metal karat — we work in solid 10k, 14k, and 18k gold, stamped — and the diamond certificate, GIA for natural stones and IGI for lab-grown, available on request. Then the written terms: deposit, returns, and warranty. If any of those three cannot be produced in writing, treat the claim as unverified rather than true.
- Is a "final sale" policy a red flag in wholesale jewelry?
- Not on its own. All sales are final with us, which is ordinary in factory-direct wholesale where pieces are made or pulled to order. What matters is what sits behind it — our warranty covers free repairs for defects in our own craftsmanship, with no fixed term. Final sale paired with a real defect warranty is a position; final sale with nothing behind it is the thing to question.
- What payment terms are normal when vetting a new wholesale supplier?
- A deposit on a first order is standard; we ask 50%, and established accounts can move to Net-15. We accept wire transfer, card, and PayPal Business. Be cautious of terms that only ever live in a conversation — written, repeatable terms matter more than the specific number.
- How can I tell a true factory-direct supplier from a reseller?
- Ask how a piece was made and set, and how the price was built. A factory answers with specifics — the QC checkpoint, the spec, per-buyer pricing — because it controls the bench. We run across Toronto, New York, and Surat, and pricing is quoted per buyer rather than marked up from a catalog. A reseller usually can't go past the product photo.
