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 titanio 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.
