Frequently Asked Questions (FAQ)
-
Q: What is the difference between 316 and 304 stainless steel for rings?
A: 316 stainless steel contains molybdenum, providing superior corrosion resistance against chlorides and acids. It is also more hypoallergenic, making it ideal for jewelry that contacts skin directly. -
Q: Can you provide a mill test certificate for each batch?
A: Yes, we issue a mill test certificate (MTC) for every production lot, verifying the chemical composition and mechanical properties of the 316 stainless steel used. -
Q: What is the minimum order quantity (MOQ) for custom rings?
A: Our standard MOQ is 100 pieces for custom orders. However, we offer lower MOQs for sample orders or prototypes—please inquire for details. -
Q: How long does production usually take?
A: Lead time depends on order quantity and customization complexity. Typically, 7-15 working days for standard sizes and finishes, and 15-25 working days for custom designs. -
Q: Can I get a sample before placing a bulk order?
A: Absolutely. We offer sample rings at a nominal cost. The sample fee can be deducted from your first bulk order if confirmed. -
Q: What packaging options do you offer?
A: We provide bulk packaging in poly bags, individual poly bags, velvet pouches, white boxes, display cards, or custom packaging per your design. -
Q: Do you offer polishing or matte finish as standard?
A: Both finishes are standard and available at no extra cost. For special finishes like brushed or PVD coating, please contact us for pricing. -
Q: How do you ensure the ring will not cause skin irritation?
A: 316 stainless steel is a medical-grade material with low nickel content, making it biocompatible and safe for most people. We recommend testing for extreme sensitivity, but it is generally hypoallergenic.
