Main Topic Explanation: What is Sterling Silver Jewelry?
The Composition of 925 Sterling Silver
Sterling silver refers to an alloy containing 92.5% pure silver and 7.5% copper or other metals for enhanced strength. At Lefeng Jewelry, we adhere strictly to 925 sterling silver standards and combine precision casting, CNC engraving, and manual polishing for crisp surface details and durable finishes.
Applications in Custom Jewelry Manufacturing
From minimalist necklaces to intricate bracelets, sterling silver jewelry offers versatility for private label and boutique collections. Our expertise as a custom jewelry manufacturer ensures each piece—whether rings, earrings, or brooches—meets your design brief and B2B requirements.
Why Sterling Silver Jewelry Matters for B2B Brands
SGS-Certified Quality and Durability
All our sterling silver jewelry undergoes rigorous SGS testing, including RoHS compliance, REACH/SVHC reports, EN1811 nickel release, and 240-hour salt spray tests. These certifications guarantee corrosion resistance and consumer safety.
Hypoallergenic and Nickel-Free Finishes
With a nickel-free electroplating process, our 925 sterling silver pieces are hypoallergenic and ideal for sensitive skin. We also offer PVD gold plating and rose gold plating options for design versatility.
Cost-Effective Private Label Solutions
Lefeng Jewelry supports low MOQ and streamlined sample development, making bulk orders accessible to emerging jewelers. Our one-stop services—from mold development to private-label packaging—ensure efficient production and competitive pricing.
