Most jewelry brand guides focus on branding, Instagram aesthetics, and pricing strategy. This one is different. This is about the part that actually determines whether your brand survives: your manufacturing partnership. Getting production right from the start saves years of painful mistakes.
Step 1: Define Your Product Before Contacting Any Factory
Don't contact a manufacturer until you can answer these questions clearly. Factories respect prepared buyers — a clear brief gets a more accurate quote, faster response, and better treatment as a client.
- What metals? Sterling silver 925, gold vermeil, solid gold (9k/14k/18k), brass — each has different price points and market positioning
- What stones? CZ, semi-precious, precious, or no stones
- Target retail price point? This determines your acceptable cost of goods (typically 20–30% of retail for direct-to-consumer brands)
- Collection size? How many SKUs for your launch collection
- Launch timeline? Reverse-engineer from your target launch date — factor in 10–14 weeks for first production
Step 2: Shortlist 3–5 Manufacturers
Don't go exclusive on your first contact. Approach 3–5 factories with the same brief and compare responses across four dimensions:
- Response speed — how quickly they reply tells you how they'll communicate during production
- Quote detail — itemized vs vague; an itemized quote shows professionalism
- Sample process clarity — can they explain the sample and approval process clearly?
- Communication quality — English fluency, clarity, willingness to answer questions

Step 3: The Sample Phase — Where You Actually Evaluate a Factory
The sample is everything. It tells you more about a factory than any website, any testimonial, any sales conversation. Order samples from your top 2 factories before committing to production.
What to check on your sample:
- Weight — does it match the specification? Lighter than spec suggests thinner metal or poor casting
- Plating color — does it match your reference exactly?
- Stone setting security — press each stone lightly; it should not move at all
- Surface finish consistency — are all surfaces finished to the same standard?
- Dimensions — does ring size match? Does pendant length match?
- Hallmarking — is 925 (or relevant mark) present and clearly stamped?
Step 4: First Production Run — Start Conservative
Even if you're confident in the designs, your first production run should be at or slightly above your MOQ. Reasons:
- You don't know real demand yet — market response will surprise you
- Gives you room to test customer response before committing to large inventory
- Minimizes financial risk if the design needs adjustment after customer feedback
- Allows you to evaluate the factory's full production quality, not just sample quality
During production — stay engaged:
- Request milestone photos after casting, after polishing, before plating
- Ask questions if anything looks different from the approved sample
- Confirm packaging before the entire run is packaged
Step 5: Building a Long-Term Partnership
The best manufacturing relationships compound over time. Here's how to build one:
- Pay on schedule — reliable payment is the fastest way to earn priority treatment
- Give clear, written feedback — vague feedback creates confusion; annotated photos work best
- Plan collections in advance — factories give better scheduling and pricing to clients who plan ahead
- Communicate openly about your growth — let your manufacturer know when you're scaling; they'll invest more in the relationship
FAQ
How much money do I need to start working with an OEM manufacturer?
For a 3-design launch collection at 30 pieces per design from a Bangkok factory: budget approximately $2,000–$5,000 total (sample fees + mold fees + first production run + shipping). This varies significantly by metal type, stone complexity, and design.
Do I need a registered business to work with a manufacturer?
Not necessarily for your first order, but you'll need one to handle import paperwork in your home country and to establish proper business terms with the factory. Establish your business entity before placing your first production order.
What if my samples need major revision?
Request a second sample — this is normal and expected for complex designs. Most manufacturers include one revision round in the sample process. Major revisions (changing the design significantly) may incur additional fees. Be specific in your revision feedback with annotated photos.
How do I evaluate if the production quality matches my sample?
Request 5–10 pre-shipment photos of random pieces from the production run alongside your approved sample. If anything looks different — plating color, stone setting, finish — raise it before the shipment is dispatched.
