We transform your copper or stainless steel sketches into meticulously crafted jewelry – precise finishes, structural integrity assured by 300+ QC touchpoints, and adherence to your exact technical specs. Scalable OEM/ODM production in flexible batches (500-50,000+ pcs) ensures seamless global compliance and consistent readiness for market. Partner beyond the supplier: Achieve brand-aligned craftsmanship without compromise.
When you have a design concept but struggle to realize it due to limited production resources, Starharvest offers an end-to-end, one-stop custom jewelry production solution to realize your design. Leveraging over 20 years of experience in custom jewelry, we provide comprehensive design development, material optimization, and process optimization. Through rigorous sample verification and quality control, we ensure that each product accurately reflects your design intent.
We support ring precision control from 0.5mm to 10mm, offering customization options for solid, hollow, and adjustable ring configurations. We also develop patented anti-oxidation lining technology for ring boxes, and a hypoallergenic plating layer certified for North American customers (compliant with SGS/REACH standards).
Provides solutions for sensitive earlobes, offering 12 safety structures including screw buckle, magnetic buckle, and silicone ear plug. Supports laser micro-engraving LOGO technology (minimum 0.3mm font).
The entire series comes standard with a break-resistant 7-strand twisted copper-core steel chain (15kg load capacity), with custom chain lengths accurate to ±0.5cm. We also support 3D precision casting of pendants (minimum 0.8cm for complex patterns) and custom development of extension chain accessories.
Patented modular structure allows for free combination of pendant/chain/locking units. New solutions include eco-friendly silicone-lined copper chain (sports style) and magnetic quick-release mechanism.
Luxury-grade titanium steel for men’s wear, precision-carved with a minimum 0.5mm relief precision. Patented non-magnetic base (compatible with medical and aviation applications), supports family crest reproduction and custom development of micro-mechanical transmission structures.
The revolutionary three-point fixed backstitch (anti-twist design) supports multi-material splicing such as enamel, resin, and epoxy. Special application scenarios include: clothing and textile embedded bases, and removable promotional badge components.
OEMの強み: .
We offer flexible options (such as die casting or lost wax) based on your design drawings, supporting both large and small-volume OEM production, addressing customer pain points such as slow prototyping and high tooling costs. Leveraging 20 years of experience to ensure consistency and tolerance control (±0.1mm accuracy), we can shorten first-sample turnaround time to just 5 days. Whether your e-commerce brand requires complex geometries or minimalist, we can match material parameters (for example, optimizing stainless steel hardness), allowing you to focus on brand design rather than production risks.
We offer custom colors, thicknesses (ranging from 0.5-3μm), and eco-friendly options (compliant with European and American REACH standards), helping you address the challenges of rapid fading and batch-to-batch color variation. Our ODM partnerships allow for rapid color iteration to match brand positioning (e.g., fast color adjustments for popular e-commerce products). Combined with stainless steel or brass substrates, our customizations extend product lifespan and reduce return rates, while also allowing for small-batch orders to test market response.
We can adjust the roughness (Ra value 0.2-1.5μm) to suit your product’s style (such as Nordic minimalist style), addressing customers’ pain point of inconsistent surface quality. Twenty years of expertise ensures batch consistency and avoids secondary processing delays. We support ODM needs for brass or stainless steel jewelry, enhancing tactile comfort and adapting to brand owners’ fast-fashion iterations, shortening your time to market.
We can incorporate your brand elements (such as e-commerce logos or cultural icons) to provide in-depth and fast adjustments, addressing issues such as low pattern accuracy or customization delays. Rapid prototyping and an accuracy of <0.05mm support small-batch OEM trial production. This is ideal for personalized upgrades of brass and stainless steel jewelry, enhancing product storytelling and helping brands stand out from the competition without the risk of excess inventory.
We offer material compatibility (such as heat-resistant stainless steel options) and precise positioning control to address customer pain points such as weak welds and poor batch yields. Our 20-year quality control system ensures a 99% pass rate (IP68 waterproof testing). Our ODM service allows you to specify assembly details (such as weld thickness), ensuring the durability of brass products in high-frequency use and reducing after-sales costs. This service is particularly suitable for the mass production needs of medium and large brands.
We support the matching of sizes and positions of various materials (such as moissanite and rhinestone), addressing issues such as inlay fallout and design limitations. Through modular ODM, we enable rapid prototyping (samples within three days) and accommodate lightweight brass and stainless steel jewelry. This helps e-commerce brands create cost-effective, blockbuster products and increase product premiums without the risk of excessive R&D investment.
Star Harvest’s custom services are designed specifically for brand owners, offering one-stop OEM/ODM solutions for brass and stainless steel jewelry. With 20 years of industry experience, we streamline the customization process, seamlessly bridging the gap from design and development to mass production. We ensure every product meets quality, compliance, and cost-optimization requirements, allowing you to focus on brand building and market expansion.
