For two decades, in the field of stainless steel jewelry, we have continuously reflected on and explored the depth and sophistication of our products, seeking the optimal balance between brand expression and market value.
In stainless steel jewelry manufacturing, many factories can produce the products, but very few can extend brand value. Truly valuable collaborations go beyond understanding “craftsmanship”; they lie in empathizing with the “brand.”
• We are deeply involved in the brand’s journey from concept to finished product.
• In an uncertain market, we provide stable delivery and flexible production capacity.
• We are committed to creating long-term value beyond the transaction in our business partnerships.
At Star Harvest, we specialize in professional and flexible OEM customization services tailored to meet your brand’s unique positioning and market demands.

All our work begins only after an NDA confidentiality agreement is signed. The entire production process is kept confidential and uses a separate, closed production line. Design documents are only delivered to the client after the order is completed to ensure intellectual property security.
We have our own quality laboratory to conduct quality testing, and we can also provide third-party testing reports to ensure that we meet global quality standards.
As a leading B2B jewelry factory, we’re proud to have established long-term partnerships with numerous high-end global fashion and jewelry brands, including renowned international retailers and designer labels. However, due to our strict adherence to non-disclosure agreements (NDAs) to protect our clients’ trade secrets and intellectual property, we cannot disclose specific brand names. This reflects our company’s strength, integrity, and professionalism—our ability to provide high-quality custom brass and stainless steel jewelry to top brands. If you’re a potential partner, please contact us through our official website to learn more about collaboration opportunities. Let’s work together to drive your brand’s success.
We employ a proprietary electroplating process to ensure our brass and stainless steel jewelry achieves the highest industry standards for surface treatment. As a professional B2B jewelry manufacturer, our electroplating process boasts superior corrosion resistance and fade resistance, guaranteeing lasting luster. (For example, the electroplating thickness meets international ISO standards and comes with a salt spray test report, ensuring a lifespan 2-3 times longer than our competitors under normal use conditions, and stainless steel is compatible with PVD plating.) We continuously optimize our electroplating process and implement rigorous quality control procedures (such as batch sampling inspection) to meet the high-end customization needs of designers and brand owners.
Our factory’s core manufacturing expertise focuses on brass and stainless steel jewelry. These materials offer excellent durability, luster, and cost-effectiveness, making them our strengths in mass-producing high-quality B2B products. In addition, we also support customization of other materials, including silver and other special alloys (such as copper alloys or environmentally friendly metals), suitable for high-end fashion designs or specific market needs. No matter what material you need, we can provide one-stop service from design to mass production.
We are a B2B factory focused on providing customized services (including OEM and ODM). We do not engage in wholesale or retail business. This means we do not directly sell inventory, accept bulk purchases of finished products (like traditional wholesale), or conduct retail transactions with end consumers. Instead, we partner with corporate clients (such as brands, designers, or retailers) to custom-produce brass, stainless steel, and other jewelry to your needs (i.e., full customization from design to delivery).
At our factory, we implement a multi-layered quality control system to ensure that every piece of jewelry meets stringent professional standards. This includes:
Material Screening: We only use brass, stainless steel, and other designated materials (such as silver) that meet industry standards. Each batch of raw materials undergoes chemical composition and durability testing to eliminate sources of inferior quality or contamination.
Production Process Monitoring: We implement spot checks and sampling throughout the entire production process (from design and mold making to surface treatment) to ensure consistency in key parameters (such as dimensional accuracy and plating gloss). Automated equipment is used to reduce human error.
Finished Product Inspection and Certification: Every batch undergoes 100% visual and functional inspection (including wear resistance, allergy resistance, and structural strength), and third-party certifications (such as SGS lead-free certification or EU REACH compliance) are provided upon request.
Continuous Optimization: We optimize our quality processes through customer feedback and regular internal audits (referring to the ISO 9001 framework).
We guarantee consistent quality, regardless of order size. If you have specific quality standards (such as environmental requirements), please contact us for a customized solution. We can provide sample test reports or provide an online consultation for immediate response!
