What We Can't Do
We'd rather be upfront than waste your time.
No precious metals. We do not work with gold, platinum, or fine silver.
No fine jewelry with gemstone setting. We are a fashion jewelry and accessories factory.
No projects without a reference. We need a drawing, photo, sample, or clear description. We don’t design from a blank page for free.
No orders below MOQ. We are a bulk manufacturer, not a sample shop.
No counterfeit or trademarked designs. We will not reproduce brand logos or protected designs.
No medical or implant-grade products. Our titanium line is for fashion body jewelry, not surgical implants.
No rush orders under 5 days. Our quality testing alone takes 2–3 days.
No certifications we don’t hold. We comply with REACH and CA Prop 65. We do not claim other certifications.
If your project falls outside these lines, we'll tell you honestly and, where possible, point you elsewhere.

OEM Process
You provide the design, we manufacture it.
01｜Design Submission & Review
The client provides complete 3D CAD files, technical drawings, or physical samples. Our engineering team reviews the design for manufacturability, including structure, casting feasibility, and stone-setting stability.
02｜Mold Development & Sampling
Based on the approved drawings, we develop the molds (wax molds or steel molds) and produce a silver or brass sample for client confirmation of dimensions, craftsmanship, and surface finish.
03｜ Sample Approval
The client confirms the final sample, including material, plating color, and stone setting. This approved sample becomes the golden standard for mass production.
04｜Mass Production & Quality Control
After sample approval, we proceed with bulk production according to the order quantity. A 100% inspection is conducted throughout the process to ensure every piece matches the approved sample.
05｜Packaging & Shipping
After finishing, plating, and packaging, we arrange global shipping.
ODM Process
We design and manufacture, you select or buy out the design.
01｜Requirement Communication & Concept Input
The client provides style references, inspiration sketches, or market positioning. Our in-house design team develops concepts accordingly.
02｜Design & 3D Modeling
Our designers deliver renderings or 3D CAD models for the client to select. If the design is bought out, we will not sell the same design to other clients; if not, we retain the right to use it.
03｜ Sample Production
Once the design is confirmed, we produce a physical sample (typically 25–30 days). The client may request modifications such as stone color or chain thickness.
04｜Revision & Final Approval
We carry out 1–2 rounds of sample revisions until the client is satisfied. The final version is then confirmed as the sales version.
05｜Mass Production
After final approval, the order enters the same bulk manufacturing and quality control process as OEM.
What It Costs
We don’t publish fixed prices because cost depends on material, process, quantity, and finishing. Here’s the structure.
