What We Can't Do
We'd rather be upfront than waste your time.
No precious metals. We do not work with pure 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｜Cooperation Preparation
Before cooperation begins, you need to:
- Review and acknowledge our payment terms, production standards, and return/refund policy
- Sign a mutual Non-Disclosure Agreement (NDA)to protect both parties
02｜Design & Technical Review
Requirements Gathering: Submission of initial design concepts, logo files, material specifications (316L stainless steel) needs. Regarding the types of design files you provide, we support both 2D design files (AI, PDF, CDR, PSD) and 3D models (STP, STEP, IGS, STL).
03｜ Quotation & Deposit Payment
Detailed Quotation: We will provide a detailed quotation within 24 hours. This includes the EXW (factory) price, mold fees (if applicable), sample fees, and shipping costs.
Pay the deposit: Please review the Proforma Invoice (PI) and pay the deposit. Once we receive the payment, we will immediately begin work on the project.
04｜3D Design & Confirm
Turn your hand-drawn sketches or reference images into CAD/3D models.
Confirm Every Detail: You can check the exact dimensions, thickness, and logo placement again before the sample is made.
Timeline: 2–5 Working Days
05｜Sample Approval
Before mass production, a physical sample is produced for approval.
We select the most suitable process based on your design and structure.
- Shaping methods include lost-wax casting, MIM, CNC engraving, stamping, or 3D printing.
- Special processes: stone setting, enamel or oil application.
- Finishing options: mirror polish, brushed texture, PVD plating (gold, rose gold, black).
06｜Bulk Production & Quality Inspection
Mass production follows approved samples with stage-by-stage quality control:
Incoming Material Inspection.
Forming & Casting: Verify dimensions and structural integrity.
Polishing: Check surface smoothness and defects.
Assembly: Confirm stone setting and specialty processes.
Plating: Test thickness, adhesion, and color consistency.
Final Inspection: Ensure appearance, durability, and function.
07 | Customer Inspection
Third-Party Inspections: Appointments can be arranged with agencies such as SGS, ITS, BV, and Intertek.
