In today’s competitive jewelry market, choosing sterling silver jewelry that balances quality, cost, and design versatility is crucial for brands and wholesalers. Lefeng Jewelry leverages 15 years of factory-direct expertise, advanced CNC engraving machines, and SGS-certified processes to deliver premium 925 sterling silver pieces. From alloy composition to final QC inspection, our detailed insights help you source with confidence and scale your private label collection efficiently.
What Is Sterling Silver Jewelry?
Sterling silver jewelry consists of 92.5% pure silver alloyed with 7.5% copper or other metals to enhance strength while retaining a bright finish. This material is prized for its balance of affordability, workability, and lustrous appearance. Unlike plated metals, sterling silver maintains its value and can be expertly polished or finished with PVD gold plating, rose gold plating, or enamel details.
Composition of Sterling Silver
- 92.5% Silver: Provides the signature shine and hypoallergenic qualities.
- 7.5% Alloy Metals: Typically copper or zinc alloy for added strength.
- Optional Coatings: PVD coating or silver finish for tarnish resistance.
Production Process Overview
Production begins with alloy preparation using precise XRF material composition reports from SGS. Melted silver is cast into molds, then undergoes stamping, cutting, and polishing. Electroplating and PVD gold plating can add color options while manual QC ensures every piece meets RoHS and REACH standards.
Why Sterling Silver Jewelry Matters
Brands and private-label sourcing managers value sterling silver for its blend of quality and cost-effectiveness. It appeals to a wide market from the US and EU to the UK, Canada, and Australia, offering a premium look without luxury brand pricing.
Durability and Hypoallergenic Properties
Sterling silver is inherently nickel-free and hypoallergenic. Combined with SGS-certified Nickel Release EN1811 testing, it meets rigorous RoHS and Salt Spray 240H corrosion resistance standards. This ensures your wholesale sterling silver jewelry is safe for sensitive skin and durable for daily wear.

From custom sterling silver necklaces and bracelets to rings and earrings, our in-house mold development, logo engraving, and stone setting capabilities cater to unique design needs and branding requirements.

Step-by-Step Guide to OEM Sterling Silver Jewelry Production
Partnering with a custom jewelry manufacturer streamlines the process from design concept to export-ready shipment. Below is a high-level workflow supported by our in-house factory.
Step 1: Design Development and Sample Making
Use CAD or hand sketches to outline your sterling silver jewelry concept. Our design team refines your ideas, develops molds, and produces 316L stainless steel model prototypes if needed. Quick sampling allows for feedback on shape, finish, and branding elements such as logo engraving.
Step 2: Casting and Alloy Preparation
SGS-certified alloy preparation ensures precise 92.5% silver composition. We employ vacuum casting or centrifugal casting methods to fill molds cleanly and minimize porosity. This stage sets the foundation for durable, high-quality silver jewelry.
Step 3: Surface Finishing and Quality Control
After casting, pieces undergo polishing, brushing, or plating operations. Electroplating or PVD processes can add gold or rose gold layers. Each batch is inspected under QC protocols for plating thickness, finish uniformity, and mechanical strength.
QC Inspection Details
- Coating Thickness Test
- Salt Spray Corrosion Resistance (240H)
- Nickel Release EN1811
- Surface Smoothness and Durability Checks
