In the world of fashion jewelry, materials dictate longevity. At Jesa Jewelry, we refuse to compromise. We have built our manufacturing standards around premium raw materials and cutting-edge plating technologies to ensure your brand delivers pieces that last a lifetime.
01. Premium 316L Steel
We exclusively utilize surgical-grade 316L stainless steel as the core foundation for our catalog. Unlike standard brass or cheap zinc alloys that easily oxidize and turn skin green, 316L steel offers unparalleled structural integrity. It is 100% hypoallergenic (nickel and lead-free), completely waterproof, and boasts incredible tensile strength to prevent delicate chains from snapping.
02. Advanced PVD Coating
Traditional electroplating fades within weeks. We employ state-of-the-art Physical Vapor Deposition (PVD) technology. This vacuum coating process bonds real 18K gold particles to the steel base at a molecular level. The result is a brilliant, rich finish that is up to 10 times more durable than standard plating, ensuring your jewelry remains tarnish-free and radiant for years.
Our 3X Rigorous QC Process
A zero-return rate is our ultimate goal. Every single piece must pass through our strict 3-stage Quality Control protocol before it reaches your inventory.
1. Raw Material QA
Before production begins, we rigorously verify the purity of the incoming 316L steel and check all casting molds for microscopic defects to ensure a flawless foundation.
2. In-Line Checking
During production, we continuously monitor the polishing phase for absolute smoothness and verify the exact thickness of the PVD gold coating in real-time.
3. Final Inspection
A meticulous piece-by-piece visual inspection under high-intensity lighting to check clasps, AAA+ Zirconia stone settings, and overall finish before sealing.
