It looks like you are referencing Guangzhou JingYing Jewelry (also known as Chingying Jewelry), a well-established custom 925 sterling silver and copper jewelry manufacturer based in China. Founded in 1998, they have indeed reached over 23 years of experience in the industry (now passing 28 years as of 2026).

They specialize heavily in OEM/ODM custom manufacturing, creating hip-hop, iced-out, and high-end fashion pieces—including men’s black onyx and micro-inlaid CZ/moissanite necklaces.

If you are looking to source from them or trying to build a custom piece, here is a breakdown of their manufacturing process and capabilities:

Core Manufacturing Capabilities

• Materials & Inlays: Primarily high-quality 925 Sterling Silver and Brass/Copper. They handle custom stone-setting using high-grade 5A Cubic Zirconia, Moissanite, and semi-precious gemstones like Black Onyx.

• Micro-Inlay Technology: They utilize specialized micro-inlay machines to securely hand-set stones into iced-out or rapper-style chains, ensuring a 99% “no lost stone” rate.

• Premium Plating (Gold Vermeil): They offer thick vacuum electroplating and water plating (up to 3.0 microns thick), which prevents premature fading and gives silver the look of solid 14K or 18K yellow/white/rose gold.

Custom Production Workflow

If you partner with them to manufacture a custom line of men’s necklaces, they typically follow this structured pipeline:

Manufacturing Turnaround

• Sample Production: ~7 Days

• Mass Production: ~30 Days

• Monthly Capacity: Up to 100,000 pieces across their Guangzhou and Wuzhou factories.

Note: If you are trying to contact them directly for wholesale orders, their standard verified digital channels are listed under their primary web domains (kingjy.com and chingying-jewelry.com).
