A practical sourcing guide for jewelry brands: when 304 is the smart commercial choice, when 316/316L is worth the higher production commitment, how our real 18K gold PVD vacuum plating is specified, and how finished jewelry should be evaluated for market compliance.
“316 is better” is too simple for B2B sourcing. The best specification depends on availability, corrosion-resistance requirements, target price and order volume.
304 is the more common base material for ready-stock stainless steel fashion jewelry. Its broad market availability makes it practical for lower-volume sourcing, faster style selection and cost-sensitive collections.
316-family stainless steel adds molybdenum for improved resistance to pitting in chloride-containing environments. It can be the right choice for specific performance requirements, but material and component availability typically means a higher MOQ and cost.
| Decision factor | 304 | 316 / 316L |
|---|---|---|
| Market / ready-stock availability | High — mainstream choice | More limited by style/component |
| Typical MOQ impact | More flexible | Usually higher |
| Corrosion resistance | Strong for everyday fashion jewelry | Higher, especially against chloride pitting |
| Cost positioning | More cost-efficient | Higher material/production commitment |
| Best sourcing use | Ready stock, testing collections, broad fashion programs | Programs where the specification justifies higher MOQ |
This is one of the most common misunderstandings in stainless-steel jewelry. Both 304 and 316-family stainless steels normally use nickel as an alloying element; 316 can even have a higher nominal nickel range than 304. What skin-contact rules evaluate is release from the finished article under the relevant test method.
Material grade can be supported by supplier documentation and, where required, material analysis. This tells us what alloy the part is made from.
For regulated markets, finished jewelry may require project-specific testing for nickel release and restricted substances such as lead and cadmium. Testing is arranged only when requested; reports belong to the commissioning customer and cannot be shared across unrelated products or buyers. Scope and cost depend on the finished design, components, production batch and destination market. Small orders do not remove applicable compliance obligations.
For EU jewelry, REACH requirements are a useful example of why the finished article matters. These reference points are not a substitute for a project-specific test plan.
CHARMOND gold-tone products use real 18K gold in the PVD vacuum plating finish. Plating thickness is a technical specification, not just a color description.
A useful compliance file is not one generic “certificate.” For B2B projects we recommend matching documentation to the material, finish, product type and destination market.
| Question | Useful evidence | What it answers |
|---|---|---|
| Is the base metal 304 or 316-family? | Material specification / material analysis as applicable | Alloy identity / composition |
| Is nickel exposure compliant? | Finished-article nickel-release test | Release under the applicable method — not just total nickel content |
| Are restricted heavy metals controlled? | Lead / cadmium test scope applicable to the target market | Restricted-substance content |
| What is the gold finish? | Approved plating specification | Gold type, color target and thickness requirement |
Not always. 316-family steel offers higher corrosion resistance, but 304 is the mainstream, widely available choice for much ready-stock fashion jewelry and usually supports a more practical MOQ and cost. Choose based on your program, not the grade name alone.
Yes, standard 304 stainless steel normally contains nickel as part of the alloy. “Contains nickel” and “releases nickel above a regulated limit” are not the same statement.
EU requirements for skin-contact jewelry focus on nickel release measured from the finished article with applicable methods. The finished product — including its surface system — must be evaluated against the relevant release limit.
Compared with common 304 ready-stock supply, 316-family components and style availability can be more limited. A project may therefore require dedicated material/component purchasing or production, increasing the commercial MOQ.
Yes. Our gold-tone products use a real 18K gold electroplated finish rather than only a gold-colored surface description.
Our typical plating thickness is about 0.03–0.06 μm, depending on product geometry and production requirements. For a specific program, the agreed specification should be confirmed before sampling/bulk production.
There is no honest universal lifetime number. Wear depends on friction, skin chemistry, sweat, cosmetics, chemicals, storage and care. We prefer to define the actual finish specification and, when needed, a relevant performance-test requirement.
Compliance documentation should match the product and destination market. Tell us the required market/standard and product type so the correct material or finished-product test scope can be confirmed.
