Jewelry Parts Explained: From Core Materials to Finished Sets
Material base and finishes for jewelry parts
In Lefeng's 15-year journey as an OEM jewelry manufacturer, the base material for most jewelry parts is 316L stainless steel due to its corrosion resistance, hypoallergenic properties, and biocompatibility. We also work with 304 stainless steel and select copper or zinc alloy components when the design requires specific characteristics. For wear-resistance and aesthetics, PVD plating in gold or rose gold adds durable color while preserving metal integrity. Finishes like enamel, zircon, crystal, and pearl accents can be integrated into parts such as pendants, charms, clasps, and ring settings. Our dedicated in-house factory ensures each batch meets strict tolerances and nickel-release standards, delivering a nickel-free experience for sensitive customers. This depth of material knowledge supports a range of private-label and wholesale programs, including custom stainless steel necklaces, bracelets, rings, and earrings.
Manufacturing capabilities and in-house control
Our capabilities span from OEM jewelry design development to sample making, mold development, casting, stamping, cutting, polishing, PVD plating, enamel color filling, and stone setting. An in-house QC team inspects every part, and logo engraving can be included for private-label programs. We maintain export-ready packaging and labeling to simplify distributor workflows. This end-to-end control supports a fast sampling cycle and reduces time-to-market for new necklace, bracelet, ring, or earring collections. For brands seeking a one-stop jewelry manufacturing partner, Lefeng provides a streamlined path from concept to bulk orders with predictable lead times and clear communication.
Why it matters for your business
Key benefit 1: SGS certifications and material safety
Quality and safety are foundational. Lefeng Jewelry holds SGS certifications including RoHS and REACH, EN1811 Nickel Release test, Salt Spray 240H, and Coating Thickness tests. These certifications provide independent validation of material composition, nickel-release behavior, corrosion resistance, and coating integrity, helping you meet regulatory requirements in the US, EU, UK, Canada, and Australia. This reliability is essential for private-label jewelry programs and wholesale orders, and it reinforces trust with your end customers who expect durable, compliant components.
Key benefit 2: Quality control and private-label packaging
With in-house QC inspection and private-label packaging, you gain consistent finishes and reliable assembly for every order. We offer flexible packaging solutions, including branded inner packaging, outer cartons, and quantity-managed packaging to suit boutique buyers, distributors, and online retailers. Our process emphasizes traceability, from raw material certificates to final QC reports, which you can share with your own customers. Private-label packaging aligns with your brand identity and reduces time-to-market for new lines.
Key benefit 3: Low MOQ and export-ready service
We understand the needs of growing brands. Lefeng provides low MOQ support for prototyping, samples, and small-scale launches, while still supplying bulk orders for established lines. Our export-ready service includes documentation, labeling, and packaging that align with global requirements, ensuring your private-label jewelry arrives quickly for North American and European markets. When you need a one-stop jewelry manufacturing partner, we combine design, sampling, production, and logistics under one roof to minimize risk and maximize speed to market.
Step-by-step guide to building your jewelry parts program
Step 1: Define your materials and finishes
Start with the core material: 316L stainless steel provides corrosion resistance and hypoallergenic properties. Confirm whether you want 316L as the base for charms and findings, or if a combination with 304 stainless steel is acceptable. Decide on finishes like PVD gold plating or rose gold, enamel colors, and the inclusion of zircon, crystal, or pearl accents. Clear material choices help our design and tooling teams estimate molds and production costs accurately. This planning supports custom stainless steel necklaces, bracelets, rings, and earrings that align with your brand identity.
