Jewelry Parts Explained for OEM Success
What are jewelry parts and why they matter
Jewelry parts are the building blocks of any piece. In stainless steel lines, common components include chains, clasps, posts, jump rings, hinges, ring settings, and stone settings. The base material choice—304/316L stainless steel—directly affects durability, hypoallergenic properties, and nickel release. With 15 years of factory experience, Lefeng provides secure sourcing for private-label and OEM programs, ensuring each part integrates with your design language. For brands exploring design options, learn how we support new design concepts and OEM/ODM services across markets.
Key components and finishes used in stainless steel jewelry parts
Our material palette includes 316L stainless steel as the base, plus 304 stainless steel, 925 sterling silver, copper, and zinc alloy for certain specialties. Finishes such as PVD gold plating, rose gold plating, enamel color filling, zircon and crystal placements, and pearl accents expand design language while preserving corrosion resistance and nickel-free properties. In our modern facility, components are produced with CNC engraving, laser marking, and precision welding to ensure reliable assembly.

Why it matters / Benefits
Quality and reliability backed by SGS certifications
Quality control is not optional—it's built into every Lefeng process. Our SGS certifications cover RoHS testing, REACH/SVHC compliance, material composition XRF, Nickel Release EN1811, Salt Spray 240H, and Coating Thickness testing. These tests confirm that our 316L stainless steel parts are nickel-free where required, corrosion-resistant, and safe for long-term wear. B2B buyers can rely on our documentation during audits and retailer onboarding, especially for private-label customers seeking consistent performance across markets. We also publish traceability data with each shipment, aligning with your RFQ requirements.
Flexible manufacturing model and fast sampling
We offer low MOQ support for prototype runs and pilot collections, enabling brands to test jewelry parts before scale. Fast sampling reduces time-to-market—often within days for core items. Our private-label packaging options ensure a premium unboxing experience while protecting the integrity of plating and finishes. This integrated approach helps jewelry brands manage seasonal collections without sacrificing quality.
One-stop production and export readiness
From design development to mold creation, casting, stone setting, and final QC, Lefeng covers the entire chain. Our export-ready packaging, labeling, and documentation streamline cross-border shipments to the US, EU, UK, Canada, and Australia. For brands seeking ongoing collaboration, we provide regular design updates and more options through our new-design page and Insights portal.
Step-by-step guide to sourcing jewelry parts
Step 1: Define your jewelry parts spec
Start with the essential pieces: which parts will be kept in stainless steel and which may require additional plating or stone settings. Define tolerances for chain width, clasp type, and post dimensions. Prepare a sample brief including target alloys, finishing options, and packaging requirements. This is the stage where you connect with Lefeng via our contact page or request a formal quote to begin RFQ and select items from our catalog.
Step 2: Choose materials and finishes
Select base materials (316L stainless steel preferred for durability and nickel-free properties), and decide on finishes such as PVD gold, rose gold, or silver finishes. For private-label lines, ensure nickel release testing is planned and that coatings meet RoHS and REACH standards. Matching stone settings (zircon, crystal, or pearl) with appropriate hardness and adhesion is critical for long-term wear. Our team assists with combinations for your necklace, bracelet, ring, and earring lines and can share options from the stainless steel necklace collection and other product families.
Step 3: Collaborate on sampling, QC, and packaging
Progress from concept to pre-production with a formal sample development cycle, mold validation, and engineering review. Our in-house QC checks verify plating thickness, adhesion, and surface finish before proceeding to bulk production. We offer private-label packaging that aligns with brand identity and regional requirements, ensuring a consistent customer experience. When ready, submit a quote request via Quote List and discuss private-label integration through our OEM/ODM services.
