Jewelry can arrive with our packaging or with customized client design.

Quality & Control – Lab testing

Metal contamination presents a consumer health and safety issue for fashion jewelry. Because of this, adult and children’s fashion jewelry must comply with Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) chemical regulations for nickel release, lead, cadmium and phthalates to be marketed in the EU. In the U.S., children’s fashion jewelry must comply with chemical limits set forth by the U.S. Consumer Product Safety Improvement Act (CPSIA) and California’s Proposition 65.  

GNJ Manufacturing Inc also conducts jewelry testing for quality and performance. We test to measure torque, tension, compression, flammability, resistance to corrosion and more. Lab Testing helps ensure your fashion jewelry stands up to repeated and prolonged wear to promote consumer satisfaction.
