Why Choose Us
19 Years of Proven B2B Experience
Since 2007, Jiman Jewelry has been a reliable production partner for international fashion labels and volume distributors. We execute your design specs on time and on budget.
100% In-House Setup
From initial 3D modeling and toolmaking to specular polishing and vacuum PVD coating, we handle every stage under one roof. This keeps your lead times dependable and quality tracking airtight.
Advanced CNC Milling & PVD Sputtering
Our turning centers cut sharp, tight-tolerance geometric details into solid steel. Our clean-room PVD vacuum lines bond real 18K gold directly to the 316L surgical steel core, ensuring enhanced resistance to daily wear, sweat, and moisture, depending on use conditions.
Quality-control procedures aligned with documented production standards
We run a strict, 4-stage quality-check framework. Our inspectors independently test raw metal chemistry, structural durability, and final polished finishes to guarantee Multi-stage QC before shipment.
Guaranteed Lead Time & Fast Sampling
Samples are ready in 10-15 days with existing molds, or 20-40 days when a new mold is required. We complete mass production within 30 days after sample approval, with penalty clauses for delayed shipments in our contracts.

What Our Customer Say
They didn’t laugh at a 100-piece order
“Back in 2020, we only needed 100 pieces. Most factories just ignored us. Jiman didn’t laugh and took the order. That first batch is still selling for us today.” Read the full case study →

A sketch that cut our returns
“On our first call, their engineer shared the screen and quickly sketched a tiny reinforcement on the jump ring. Said it should stop most of the returns. He was right — returns dropped a lot.” Read the full case study →
David R.
They said PVD would last longer, and it did
“Most factories just say yes to everything. Jiman said no to our original plating request and explained why PVD would last longer. Turned out they were right.” Read the full case study →

Photos before shipping, not after we complain
“We’ve ordered from factories in five different countries over the years. Jiman is the only one that sends photos before shipping — not after we have to complain.” Read the full case study →

A reply at 11 PM, 40 minutes later
“Our launch got moved up suddenly. I emailed them at 11 PM my time, just hoping someone would see it. They replied in about 40 minutes saying they could do it and explained how. That’s why we’re still working with them.”
