We not only provide basic OEM production services, but also build a complete SH service system from market trend insights, flexible production to stable production capacity guarantee, making production delivery more efficient and product design more in line with market demand. Whether it is a mature e-commerce brand or a fast-growing e-commerce brand, StarHarvest can provide fast response, differentiated technology and zero-risk supply chain support, truly achieving seamless connection from ” design concept to product shelf”.
Since 2005, we have been focusing on the production of brass/stainless steel jewelry with mature technology and stable quality.
A minimum order of 200 pieces / item , quickly responds to the needs of emerging brands, and reduces inventory pressure.
From design to sample, the average cycle is 7-15 days, which can shorten the development cycle and speed up the product launch.
From material procurement, production and processing to quality inspection and packaging, all are completed in our own factories to ensure stable delivery and quality
We provide special electroplating, laser engraving, texture patterns and other self- developed technologies to help your brand establish exclusive product tonality.
Unique SH-P quality system and multi- step QC process ensure that each product meets your needs and reduces quality issues.
Sufficient production capacity allows timely stocking regardless of peak or off-peak seasons, helping you respond efficiently to changes in market demand.
We provide professional and flexible OEM customization services, from raw materials to finished products, to ensure that each product meets your market positioning and brand tone. Whether it is a new design and development or an existing product optimization, we can create products with stable quality and reliable delivery according to your needs .
We specialize in OEM/ODM customized production of brass and stainless steel (316L/304) jewelry, providing full-process customization of material hardness, thickness, surface treatment (polished/brushed/vintage/PVD gold-plated rose gold, etc.), and can quickly produce samples within 7-10 days to verify the feasibility of the design. At the same time, we support environmentally friendly coatings and low-sensitivity alloys to ensure that products meet global market standards.
Over 20 years of experience in jewelry customization, with a total of 12,000+ brass/stainless steel styles developed. Industrial-grade 3D scanners (±0.03mm accuracy) achieve millimeter-level restoration of design drafts, maintaining material hardness and color consistency from samples to bulk goods. Each product design provides NDA agreement signing, sample packaging material development and export compliance certification hosting. You only need to focus on design, and leave the rest of the production supply chain to us for execution.
SH provides a variety of gemstone options, including natural gemstones directly mined from mines/laboratory-grown diamonds/artificial gemstones. You can freely choose according to your needs. All gemstones are certified with IGI/GIA dual certificates, and support customized solutions from special-shaped cutting to micro-setting processes, as well as complying with RJC system metal traceability standards. 48-hour ultra-fast proofing reduces development risks.
We can provide various electroplating layers, such as 10k, 14k, 18k, 22k according to your needs, and support various electroplating color options such as single color, multi-color, gradient, etc. The use of SH-type vacuum coating technology can achieve electroplating color retention > 3 years wear test cycle (in line with en 12472 artificial sweat test), the special color plating solution library supports accurate restoration of metal color numbers, and the electroplating solution ingredients can be traced, and simultaneously meet the rohs/reach heavy metal migration control requirements.
Supports the design and development of 127+ jewelry accessories such as chains, clasps, and link rings. Years of fine processing and manufacturing experience ensure lead-free solder joints and Astm F2923 tensile strength standards. Equipped with german precision cutting equipment, jewelry accessories can achieve a processing tolerance of less than 0.1mm, logo stamping and packaging materials one-stop customization, and supports a variety of materials such as brass and stainless steel, in compliance with annex xvii of reach regulations.
Over 20,000+ brass and stainless steel basic style libraries, you can choose any modification, including logo stamping, size adjustment, accessory replacement, font elements, pattern customization and other requirements. All products meet environmental certification and can provide corresponding quality inspection reports, and comply with ISO 9001 quality system and Amazon FBA packaging specifications, helping you to quickly distribute products with minimal development costs.

Copper/stainless steel raw materials entering the factory must be inspected. The inspection content includes verification of component report, surface finish, and hardness to ensure that the metal raw materials comply with ROHS & REACH standards and control quality from the source.
3D scanning compares the design drawings to check the wax model size error (within ±0.1mm), hollow details, and overall proportions to prevent later rework caused by mold deviation.
After casting, the embryos are 100% inspected for trachoma, bubbles, and deformation, and the internal structure is inspected by X-ray to ensure there are no invisible defects.
Double inspection by manual and machine ensures that the welding points are firm, the lines are smooth and free of burrs, and the surface flatness meets the standards (sampling rate 30%, 100% for high-risk models).
Check for residual stains after ultrasonic cleaning, test surface adhesion after pickling, and compare the color plate with the opponent’s plate to avoid color difference after electroplating.
Salt spray test + abrasion test sampling, visual inspection of mirror/matte process halo uniformity, coating thickness meter detection (0.03μm accuracy), additional test of anti-fingerprint layer.
Both functionality and aesthetics are ensured – fastener opening and closing tests are conducted 500 times, stone setting firmness is tested through vibrations, scratches/discoloration are checked visually, and AQL inspection reports for each batch are kept on file.
Check order requirements (lettering, accessories, packaging), use metal detectors to check for residual debris, scan anti-theft labels/environmental labels one by one, and conduct a second random inspection before sealing the box
