Reason 1
SPEC FREEDOM
Two chains that look equally thick can differ 40% in weight — and you pay by the gram, not the millimeter. Give us your target cost; we'll work backward to the gauge.

May You Ask
You buy chain by the roll, but your customer judges it as a finished piece. These five decisions move your cost andyour return rate more than the chain type ever will — and we work through every one of them with you.
Reason 1
Two chains that look equally thick can differ 40% in weight — and you pay by the gram, not the millimeter. Give us your target cost; we'll work backward to the gauge.
Reason 2
Chains bought separately don't just mismatch in color — the plating thickness differs. Six months later the chainhas worn through while the pendant looks new, and your customer assumes it was fake.
Reason 3
If the chain just carries a pendant, don't pay for a mold. If the chain is the product, a stock profile anyone can buyis a price war you can't win.
Reason 4
On a bezel or rhinestone chain, one loose stone is the number-one reason the finished product comes back. Everylot is pull-tested before it ships — and we'll tell you the standard we test to, which most factories won't put anumber on.
Reason 5
18" sells in the US, 45cm in Europe, shorter in Asia. A 2" extender covers all three — one SKU instead of three, andfewer dead stock sizes.
We're constantly raising our own standard — better craftsmanship, better materials, better finishes, and tighterchecks before anything leaves the factory. That's why more jewelry brands, retailers and designers keep choosingto work with Jinnuo. Here are a few of them.
