GNJ Manufacturing has served the jewelry industry since 1999, bringing together design, product development and factory production for retailers and e-commerce brands worldwide. Our work spans body piercing, women’s jewelry and men’s jewelry, from everyday steel pieces to decorative, stone-set styles.
Our U.S. design team follows jewelry trends and develops ideas for retail assortments. The Huizhou factory brings those ideas into production. That connection between design and manufacturing is central to GNJ’s business: helping retail partners develop jewelry around their category, brand and product requirements.
With more than 25 years of OEM and ODM experience, GNJ works with both retailer-supplied designs and custom product development. A collection can begin with an existing GNJ style, a sketch or a reference photograph.
Inside our Huizhou factory
From a design brief
to the workbench.
Our factory is based in Huizhou, Guangdong, China. Its production work connects digital design with the hands-on processes that shape, set and finish jewelry. The steps vary by style, with design review and product approvals before manufacturing.
Design with your assortment in mind
Design collaboration spans the U.S., China, Mexico and Europe, bringing several market perspectives to development. Share your category, intended customer and visual direction. Work can start from your own concept or a GNJ style, with proportions, components, finish and stone details reviewed as the design develops.

GNJ’s assortment includes stainless steel, plated brass, acrylic and other materials. Steel styles include grades such as 304, 316 and 316L, depending on the item. A complete specification identifies the material of each component, finish, stone accents, dimensions and piercing gauge.

Quality & responsible manufacturing
The product matters.
So does the factory behind it.
GNJ’s manufacturing approach includes product approvals, quality control and laboratory testing. For a retail program, the conversation starts with the specific style, its components and the requirements of the destination market.
Retailers also need visibility into the business and facility they are evaluating. Our documentation library brings together published jewelry sample reports and GNJ’s Higg FSLM self-assessment record. Request current records for the product, factory and audit requirements in your vendor review.
For vendor review
