How OEM and ODM Jewelry Costs Differ
OEM and ODM quotes are built from different lines. On an OEM job you own the design file and the factory prices the making, so the money sits in metal, tooling and bench time. On an ODM job the factory also supplies the design work, which pulls the 48-hour CAD stage and the 25-30 day sampling window into the price. Published minimums are 100 in artisan brass, 50 units in sterling silver and 100+ pieces in the stainless line, counted per design, and they hold design by design.
Key takeaways
- OEM prices the making of a file you own; ODM prices design development on top of the making.
- 3D CAD clears in under 48 hours on both routes, so drawing time is not where the cost gap lives.
- Sampling takes 25–30 days and mass production 3–4 weeks, whichever route you are quoted.
- Entry quantities are 100 units in artisan brass, 100+ pieces in stainless and 50 pieces in sterling silver, design by design.
Two routes, two cost centres
Split the invoice in half and the picture gets clear. One half is the work the factory can only start once your design exists: mould making, casting, sprue cutting, polishing, surface finishing and electroplating. The other half is the work that produces the design in the first place: technical drawings, virtual renderings and a physical master that has to survive your approval.
OEM means you arrive with the design, so you buy the first half. ODM means you arrive with a mood board or a rough drawing, so you buy both halves and the factory carries the design risk. Neither route is cheaper in the abstract; they are cheaper for different kinds of buyers.
Where the money goes on an OEM route
If you hand over a tech pack you have already paid for the design, usually with a freelance CAD modeller. What you are buying next is repeatable production: a mould that holds its dimensions, a plating stack that does not discolour, and an inspection pass before the carton is sealed. Because you own the file, that work is quoted as a making charge plus material, and it scales almost linearly once the mould exists.
This is the route most run by brands with a product developer on staff. It is also the route where a private label OEM jewelry manufacturer expects to receive industry-standard files rather than inspiration, because there is no design fee to absorb the interpretation work.
Where ODM adds a line to the quote
The ODM line item is development. It covers concept sketching, the 3D CAD model and its renderings inside 48 hours, and then a physical master inside the 25–30 day sampling window. You are paying for five bench operations in that window: wax printing, mould casting, stone setting, polishing and electroplating.
The return on that spend is speed and exclusivity. Design, mould and CAD files stay with your brand under a 100% NDA, so the collection is not resold as a catalogue item. For a small label with no in-house designer, paying for development once is usually cheaper than hiring, because the alternative is unbounded revision cycles on a design that was never buildable.
The minimums that decide your first invoice
Whatever the route, quantity sets the unit number. Silver tooling is the least demanding, which is why stainless work, 925 silver and artisan eco-brass runs through PVD vacuum plating and a harder machining setup, so it starts at 100+.
A brand testing a single hero design in silver can therefore commit to half the pieces it would need in brass. That is the single largest difference between two first orders built from the same CAD file.
| Cost driver | Published figure | Which route it lands on |
|---|---|---|
| Design development (CAD) | under 48 hours | ODM only |
| Master sampling window | 25–30 days | Both routes |
| Mass production block | 3–4 weeks | Both routes |
| Silver minimum per design | 50 pcs | Both routes |
| Brass / stainless minimum | 100 / 100+ pcs | Both routes |
Compliance paperwork is a fixed cost, not a variable one
Certificates do not scale with order size. ISO 9001:2015 certification, REACH restrictions on lead, cadmium and nickel and a BSCI social audit, cadmium and nickel, and the plating claims sit under the same heading.
For a buyer, the practical effect is that the compliance pack costs the same whether you order 50 pieces or 5,000, so it is worth asking for early rather than at checkout. The dated documents behind the claims are what a retailer's own compliance team will ask to see.
The three numbers worth asking for first
Before any quote is comparable, ask for three published figures: the minimum per design, the sampling window and the production window. Minimums run 100+ pieces in stainless, 50 in 925 silver and 100 pcs in the eco-brass line, design by design, so a range of two designs is priced twice over.
Those three numbers do more work than a unit price, because they tell you the size of the commitment and the length of the calendar behind it. A supplier who cannot answer all three from memory is quoting a process they do not run.
Where a private-label brand can save without cutting the product
There are four honest savings in a jewellery programme. Run the pilot in the metal with the lowest minimum. Share findings, chains and clasps across several designs so fewer new moulds are needed. Specify packaging while the CAD model is being approved rather than after the sample. And keep the specification fixed once it is approved, because every change re-runs the five bench operations inside the sampling window.
What is not an honest saving is skipping the sample or the inspection stage. A BSCI audit, REACH compliance on lead, cadmium and nickel and the ISO 9001:2015 standard, cadmium and nickel are the parts of the programme a retailer will ask to see, and they cost the same at 50 pieces as at 5,000.
Worked example: what the same mould costs two buyers
Use the published minimums as the yardstick. Say a design is tooled once and runs at the silver minimum of 50 pieces against a brass minimum of 100 pieces. The fixed part of the order - making the mould, running the sample, approving the plating - is paid once in both cases. Spread over 50 pieces that fixed block is 100 ÷ 50 = 2, twice as heavy per unit as it is over 100 pieces.
Now add the design half. An ODM buyer also pays for the CAD stage and the sample, which the OEM buyer brought with them. So the ODM cost per unit is the same fixed block divided by the same 50 or 100 pieces, plus development divided by that quantity. The only way to shrink that second term is to order more pieces of the same design, or to arrive with files you already own.
Frequently asked questions
Is ODM more expensive than OEM by definition?
Not by definition. ODM adds design development to the bill, but it removes the cost of hiring or contracting that work yourself, and the tooling and production figures that follow are the same on both routes.
Which route suits a brand with no designer?
ODM, because the factory produces the concept, the 3D CAD model inside 48 hours and the physical master in 25–30 days, then keeps the design exclusive to your brand under a 100% NDA.
What quantity does a first order need?
The minimums are 100+ pcs in stainless, 100 in the eco-brass line and 50 in sterling silver, by design, with each design counted separately.
Reading a quote before you compare it
A quote only compares cleanly once you know which halves of the work are inside it. Ask for the making charge and the development charge as separate lines, then ask whether the mould and CAD files are exclusive to you. The shop floor walkthrough shows the eight stages that make up the making charge, and the wholesale programme sets out how repeat orders are handled once a design is tooled.
The figures used above — the master-sample benchmark, followed by the 24-hour response commitment — are drawn from the brand's own pages at tttjewelry.com itself, checked 28 Sept 2026.
