We offer a one-stop manufacturing solution – in-house CAD/3D design and prototyping, precision casting (in silver, gold, brass, etc.), expert stone-setting, plating and finishing. Each step is engineered for durability and aesthetics, ensuring your specifications are met.
2
Our ISO-certified process includes multi-stage inspections (12+ quality checks) and XRF/SGS testing to verify metal purity and plating consistency. We use IGI-certified lab-grown diamonds and RoHS/REACH-compliant, nickel/lead-free materials for ethical, safe jewelry.

We accommodate both startups and large brands – with low MOQs (e.g. 50 pcs silver) and high production capacity (150k+ pcs/month). Quick sampling (1–4 weeks) and efficient prototyping mean faster product launches and seasonal orders.

We protect your designs with NDA agreements and provide custom branding (packaging, tags, certification). Global shipping is fully insured (to USA, EU, Middle East, etc.) and backed by lifetime after-sales support, ensuring your peace of mind.
With over 20 years of experience and a factory of 200+ skilled craftsmen, we deliver precision jewelry manufacturing. Our facilities hold ISO 9001:2015 and RJC/BSCI certifications, reflecting our commitment to ethical sourcing and documented quality systems. All raw materials (metals and stones) are fully traceable and comply with RoHS/REACH standards. We enforce strict confidentiality (NDA-protected designs) to safeguard your intellectual property.
Quality control is built into every stage of production: each piece undergoes 12+ inspections and advanced testing. We use XRF and SGS equipment to confirm metal content (e.g. 92.5% purity for sterling silver) and monitor plating thickness. Our gemologists source certified lab-grown diamonds to IGI standards, guaranteeing consistent color and clarity. These rigorous processes and third-party audits give B2B clients confidence in the durability, compliance, and provenance of every jewelry piece we produce.
