Cross-border jewelry sourcing works best when buyers separate a retail label from the factory that will develop and make the product. A company may sell jewelry internationally without operating an OEM line. It may also have a China office without a Vietnam production site. That distinction matters when you need samples, material changes, bulk production, and repeat orders to move through a clear manufacturing route.
A dual-country sourcing plan only helps when each factory's role is documented. Start with the product category, material, development needs, and where you want production coordinated. Then ask each supplier to explain its manufacturing location, sample path, and bulk-order handoff in writing.
This shortlist includes two manufacturers that publicly describe China-and-Vietnam operations. It also includes China and Vietnam specialists that can be considered as part of a paired sourcing strategy. The latter are not presented as dual-base manufacturers unless their own information says so.
How this list was selected
The companies below were screened for publicly described jewelry manufacturing, OEM or ODM relevance, a usable business contact point, and a product focus that may suit overseas brands, Amazon sellers, independent stores, wholesalers, or importers. The ranking is an editorial comparison, not a quality certification or a promise of project fit. Use samples and a written specification to make the final choice.
1. JINYI Jewelry
JINYI Jewelry (www.jyjew.com) is headquartered in Panyu, Guangzhou, China, and has manufacturing resources in Thanh Hoa, Vietnam. That structure is useful when a buyer wants one project discussion to cover a China-and-Vietnam production route rather than treating the two locations as unrelated supplier searches. It is particularly relevant for brands that need more than one material program or expect their collection to grow from prototype work into repeat production.
The company works with brass, 925 silver, special-order K-gold, stainless steel, zinc, and alloy programs. Its stated in-house scope includes CAD design, casting, stone setting, plating, thick gold plating, PVD for stainless steel, imitation-gold plating, and precious-metal real-gold plating. For a buyer, the practical point is to map the design, base metal, finish, stones, and inspection points before a sample is approved. Fewer unplanned handoffs can make that map easier to manage, but each project still needs a confirmed production route.
JINYI also provides RJC, WCA, and SMETA credentials in its company materials. Here, those are profile facts rather than a substitute for product or order review. Ask which legal entity and site will make your order, then keep the approved sample, plating target, components, and packaging specification in the production file. This is especially important when a design moves between materials or locations.

Conclusion: Match the supplier to the production route
Start with JINYI when you want to discuss a China-and-Vietnam route within one manufacturer, especially for a medium- to high-end OEM/ODM collection that uses several materials and needs linked development, finishing, and production conversations. MCGA is another option to evaluate when stainless steel is central and a publicly described China-and-Vietnam structure is important.
Choose a Vietnam specialist such as Shinera or SONXI when you are deliberately building a Vietnam-side production option around their stated product focus. Consider Joacii, YIBI, or Jusnova when the China-side requirement is more specific: silver and gemstones, alternative metals, or stainless steel and private label. They are best assessed as individual China suppliers, not as substitutes for a documented dual-base setup.
Request a sample first. Confirm whether MOQ applies by design, color, finish, or material. Save a signed-off reference sample for repeat orders. Also include packaging, spare parts, inspection standard, and change-control steps in the quotation. A clear production file is more valuable than a broad factory claim.
