About Haosen Fashion Jewelry Manufacturer
Haosen is an audited OEM/ODM China jewelry manufacturer focused on Fashion Jewelry & Garment Accessories We work with global brands, wholesalers, and designers to develop and produce customized jewelry collections, from concept development to mass production. With years of experience in metal jewelry manufacturing, we focus on delivering stable quality, flexible customization, and reliable production support for long-term brand partners.
My journey in this industry began when Jasper was 26 years old.
I started on the ground floor as a craftsman, specializing in the delicate art of Semi-Precious Stones (Agate, Mother of Pearl, Tiger’s Eye) and Manual Inlaying.
During this time, I personally learned the art of Manual Inlaying—perfecting how to fit natural stones into metal bases without gaps or glue failure.
I also worked on the front lines of sales. In the early days of my startup, I didn’t just make the products; I sold them. I spoke face-to-face with buyers, listened to their frustrations about fallen stones and fading colors, and understood exactly what the market needed.
Over the years, this passion evolved into a mission to provide world-class OEM/ODM Jewelry Manufacturing solutions.

Achieve No-Fade Jewelry with Our Finishing


We recognize that tarnishing and oxidation are the primary concerns for jewelry buyers. To solve this, we apply material-specific protective technologies. For standard stainless steel jewelry, we use PVD vacuum plating at approximately 0.03μm. For custom stainless steel jewelry, we offer a thicker plating range from 0.06μm to 0.1μm to ensure every piece passes a rigorous 72-hour salt spray test. For Brass and Alloys, we add a professional E-Coating (Electrophoretic Coating) layer over our 0.03μm-3 μm real gold plating. This “invisible shield” effectively seals out air and moisture, preventing base metal oxidation and ensuring long-term color retention.
Our commitment to durability extends to high-performance materials. Titanium items are crafted via high-precision CNC machining to maintain hypoallergenic properties while achieving an ultra-smooth, comfortable finish. Tungsten undergoes diamond-wheel polishing for a scratch-proof, mirror-like luster that never loses its brilliance. Furthermore, as manual inlay experts, we utilize meticulous craftsmanship to secure stones—whether setting Agate into steel or Zircon into brass—eliminating the risk of stone loss at the source.
