About US

Welcome to Dongguan Hollysen Jewelry Co., Ltd., located in the heart of China's premier stainless steel jewelry hub in Dongguan Changan.

We are a China-based stainless steel manufacturer specializing in high-reliability clasps and OEM jewelry production for EU and US markets.

Our core strength lies in engineering-driven manufacturing, focusing on smooth operation, tensile strength, structural stability, and batch consistency.

We supply clasp solutions for Cuban and tennis chains, daily-wear jewelry, pet products, and accessory hardware. In addition, we support stainless steel jewelry production including chains, bracelets, rings, earrings, and pendants.

With in-house design, 3D prototyping, casting, and our own vacuum plating facility, we manage structural development and surface finishing within one integrated system.

We aim to be a reliable long-term manufacturing partner, not the lowest-price supplier.
