At JIAINUS, we stand behind the craftsmanship and material integrity of every piece of jewelry we create. Our goal is to provide your business with reliable, high-quality piercing jewelry that meets international safety standards.
We provide a Lifetime Guarantee on the authenticity of our primary materials:
S925 Sterling Silver: Guaranteed to contain at least 92.5% pure silver, finished with rhodium or 14K/18K gold plating for enhanced durability.
F136 Titanium / G23 Titanium: Guaranteed to be implant-grade, nickel-free, and biocompatible, suitable for initial piercings and sensitive skin.
If any item is laboratory-proven not to match the specified material, we offer a 200% refund or immediate replacement.
We provide a 180-day limited warranty from the date of delivery covering manufacturing defects, which include:
Structural Failures: Broken posts, hinges, or clasps under normal usage.
Setting Defects: Loose or fallen stones (Cubic Zirconia, Opals, etc.) due to faulty settings.
Threading Issues: Internal or external threading misalignments that prevent proper closure.
To maintain a fair business environment, our warranty does not cover:
Normal Wear and Tear: Scratches, dullness, or natural oxidation (tarnish) of silver over time.
Mishandling: Damage caused by improper sterilization (excessive heat), accidental drops, or over-tightening.
Third-party Alterations: Any jewelry modified or repaired by someone other than JIAINUS.
Lost Items: We are not responsible for lost jewelry or components (e.g., lost balls or backings) after the product has been used.
