Guangzhou 316L jewelry manufacturers should be compared by material specifications, development capability, finish quality and project requirements—not only by unit price. For UK and EU buyers sourcing necklaces, bracelets and earrings, confirm component materials, private tooling, logo customization, PVD finishes and quantities per design before placing an order.
This guide explains how to prepare an OEM/ODM inquiry, compare quotations and plan a custom collection with a target quantity of 300–500 pieces per design. Actual MOQ must be confirmed for the individual project.

1. Verify the Manufacturer Behind the Guangzhou Address
A Guangzhou business address does not establish where production takes place. Confirm the legal company name, factory address and manufacturing responsibilities before arranging a visit or paying for sample development.
Public supplier pages identify stainless steel jewelry businesses in Guangzhou, including Panyu. Published factory descriptions are starting points for verification through company documents, samples and a production visit or video review.
- Confirm which legal company will issue the quotation and invoice.
- Ask where molding, polishing, coating and assembly take place.
- Identify subcontracted processes and who controls their quality.
- Request a production walkthrough relevant to your proposed products.
- Confirm the production address before arranging a factory visit.

2. Specify 316L Necklaces, Bracelets and Earrings by Component
A complete-product specification is more useful than a general “316L jewelry” description. Confirm the required material for each component and record any exceptions before sampling. Do not assume that all catalog products or all components use the same steel grade.
316L Stainless Steel Necklaces
Define the chain style, length, width, pendant dimensions, clasp type and extension chain. Confirm the material of the chain, pendant, clasp and connecting rings. Include logo position and finish requirements in the quotation brief.

316L Stainless Steel Bracelets
Define wrist size, link dimensions, adjustment range, clasp construction and target weight. Confirm the material of links, charms, clasps and connectors. For adjustable bracelets, specify both the minimum and maximum wearable length.

316L Stainless Steel Earrings
Define dimensions, weight per pair, closure type, post dimensions and decorative details. Check the bodies, posts, backs and hinges separately. Confirm whether the quoted quantity refers to individual earrings or pairs.

3. Choose Between OEM, ODM and Logo Customization
The appropriate development route depends on how much of your design already exists. Confirm the supplier’s service scope, deliverables and design rights before starting development.
Existing Style with a Custom Logo
This route starts with an existing product. Provide the selected SKU, logo file, preferred finish and packaging requirements. Confirm the marking method, logo size, position and any additional MOQ.
Modified ODM Design
This route uses an existing design or a jointly developed concept as the starting point. Confirm requested changes to dimensions, stones, components or finishes, together with development charges and any exclusivity agreement.
New OEM Design
This route generally starts with your drawing, CAD file, physical sample or detailed brief. Confirm production feasibility, tooling requirements, sample revisions and manufacturing specifications before approving bulk production.
A reference photograph can start the discussion, but dimensions, construction details, material requirements and finish references are usually needed for an accurate quotation.

4. Confirm Private-Mold Ownership and Exclusivity
Paying a tooling fee does not automatically establish ownership or exclusive use. Record the agreed terms in the quotation or manufacturing agreement.
- Identify the molds or tools being developed.
- Confirm tooling fees and the included revision scope.
- State who owns the tooling after payment.
- Define whether it may be used for other customers.
- Agree on storage, maintenance and transfer arrangements.
- Clarify whether exclusivity covers the tooling, finished design or both.
Ask which parts require new tooling and which use standard components. This helps explain development costs and makes future reorder requirements clearer.
5. Specify Gold, Silver and Black Finishes Separately
Each color should have its own approved finish specification. “Gold plated” alone does not establish that the process is PVD, and a silver appearance may come from polished natural stainless steel rather than a coating.
Gold PVD Finish
Confirm the proposed coating process, gold tone, surface preparation and layer specification. Approve a physical color reference where possible so that the manufacturer has a clear target for sampling and production.
Silver Stainless Steel Finish
Specify whether you require polished natural steel or a coated silver-tone finish. Confirm brightness, texture and surface consistency rather than using “silver jewelry” as the only description.
Black PVD or Ion-Plated Finish
Ask whether the black appearance comes from PVD/ion plating or another treatment. Confirm shade, gloss level, coverage and the proposed coating specification before approving the sample.
Also confirm whether coating is performed in-house or by a subcontractor. Ask how the supplier controls color consistency between samples, bulk production and repeat orders. Durability depends on the product, coating specification and use conditions.
6. Plan a 300–500-Piece Custom Order
There is no single MOQ for every custom jewelry project. Confirm quantities per design, color and size, as well as separate minimums for components, logos and packaging.
Planning example: An order of 500 pieces in one design could be allocated as 200 gold, 200 silver and 100 black. This is a hypothetical allocation, not a confirmed Yanluo MOQ. The manufacturer must review whether each color quantity is workable.
- Request quotations for both 300 and 500 pieces per design.
- Show the planned quantity for each color and size.
- Separate sample, tooling and logo charges from unit prices.
- Confirm packaging quantities and development requirements.
- Ask whether repeat orders have different minimums.
- For earrings, confirm whether prices and quantities are per piece or per pair.
A low MOQ advertised for an existing style may not apply to a new private-mold project. Compare the conditions for your actual design.
7. Review Product Documentation for UK and EU Buyers
Testing discussions should relate to the finished products you intend to sell and the requirements of the destination market. Ask what material documentation and product test reports are available for each proposed design.
- Check the tested sample description and product reference.
- Confirm whether the tested material and finish match your proposed order.
- Review relevant nickel release, lead and cadmium test coverage.
- Confirm the report date and issuing laboratory.
- Agree whether additional testing is needed before production or shipment.
A report for one jewelry item does not automatically cover other designs, components or finishes. Confirm document availability and applicability during project review.
8. Send a Complete Brief for Comparable Quotations
Send each manufacturer the same brief so that quotations cover equivalent products. A lower price is meaningful only when material, construction, finish, branding and packaging are comparable.
- Design: Reference images, drawings, CAD files or a physical sample.
- Material: 316L requirements for each component.
- Dimensions: Length, width, thickness and target weight.
- Finish: Gold PVD, natural or coated silver, and black finish requirements.
- Quantity: Units per design, color and size.
- Customization: Logo method, private tooling and packaging.
- Documentation: Destination market and requested testing information.
- Schedule: Sample deadline and target delivery date.
Separate sample development, bulk production and shipping time. Confirm which approvals start the production schedule and how specification changes affect cost and timing.
Frequently Asked Questions
Can a Guangzhou manufacturer accept 300–500 pieces per design?
Some projects may be workable at this quantity, but acceptance depends on design complexity, tooling, components and finish allocation. Request a project-specific quotation.
Can I start with only a reference photograph?
Yes. A photograph can start the discussion, but dimensions, material, construction and finish details are usually needed before an accurate quotation and sample plan can be confirmed.
Is logo customization the same as private-mold production?
No. Logo customization can use an existing product. Private-mold production involves dedicated tooling for specific design elements, with ownership and use terms agreed separately.
Does silver-colored 316L jewelry always need PVD coating?
No. Polished natural stainless steel can provide a silver appearance. Confirm whether your design requires natural steel or a coated silver-tone finish.
Can I visit Yanluo Jewelry in Guangzhou?
Factory visits are available by appointment. Contact our team to confirm the Huadu location and arrange your visit.
What should I approve before bulk production?
Approve the sample, component materials, dimensions, finish, logo, packaging, quantity allocation and testing plan. Keep the approved specifications in writing for production and future reorders.
