Explore our showcase of advanced craftsmanship, combining GRS-certified precious metals with immaculate stone setting.
Founded in 2009 and located in Panyu, Guangzhou—the undisputed epicenter of the global high-end jewelry manufacturing industry—Guangzhou Locke Jewelry Co., Ltd. stands as a premier integrated enterprise. We specialize in the conceptualization, digital layout design, master casting, precision setting, and global supply chain logistics of high-end women’s jewelry.
With over 15 years of industry expertise, Locke Jewelry has consolidated its market position as a trusted manufacturing partner for brands, designers, and major wholesale distributors across more than 50 countries. Our operational methodology bridges the gap between heritage-driven craftsmanship and modern, automated CAD-CAM jewelry systems, allowing us to maintain aesthetic excellence and strict mechanical standards.
How we apply automated precision technology and advanced materials engineering to push the boundaries of intricate silver jewelry manufacturing.
We have integrated ultra-high resolution Digital Light Processing (DLP) and Stereolithography (SLA) 3D wax printers. This allows for rapid prototyping of intricate patterns down to 25-micron layers, ensuring that fine lace detailing, lattice work, and complex geometric matrices are cast without material distortion.
By utilizing premium, custom-formulated master alloys mixed with 99.9% pure silver, we neutralize the primary causes of silver oxidation. Our molecular engineering increases the hardness of our 925 sterling silver, ensuring superior resistance to scratching, bending, and everyday wear.
Every cubic zirconia, moissanite, and lab-grown gemstone is set under 40x magnification microscopes. This ensures that the shared-prong, pavé, and channel settings are perfectly aligned, eliminating loose stones and providing a smooth surface that does not snag on fabrics.
As global regulations tighten, Locke Jewelry leads the industry in sustainable manufacturing, ethical material sourcing, and carbon footprint reduction.
We provide options for Global Recycled Standard (GRS) certified 925 sterling silver, allowing brands to appeal to eco-conscious consumers while maintaining the structural and aesthetic integrity of virgin silver.
Our facility utilizes clean electroplating loops. Heavy-metal collection and closed-circuit water recycling reduce toxic effluents to zero, aligning with global green initiative protocols.
All natural and lab-grown stones used in our manufacturing pipeline comply with the Kimberley Process and are sourced from verified clean supply lines, ensuring fair labor and sustainable mining practices.

Our 3,000 square meter factory is equipped with advanced industrial-grade machinery, ensuring consistent density, high-precision engraving, and perfect polishing finishes for every production batch.
Navigating regional trade regulations, environmental standards, and quality certifications for seamless import/export.
Our jewelry is strictly formulated to be nickel-free, lead-free, and cadmium-free. We verify our batches through third-party laboratories to ensure full compliance with the European Union's REACH regulation and California's Proposition 65.
Guangzhou Locke Jewelry complies with international labor standards, carrying certificates from BSCI, SGS, ISO 9001, and the Disney FAMA audit, ensuring ethical working environments and secure production facilities.
To facilitate smooth global delivery, we offer comprehensive customs classification codes (HS Codes), compliant packaging labels, and direct commercial invoice configurations, reducing import clearance times down to 48 hours.
Supporting jewelry brands, online storefronts, and major distributors with scalable options and specialized logistics solutions.
Answers to technical, logistics, and production inquiries from global procurement managers.
We use strictly certified 925 sterling silver, containing 92.5% pure silver and 7.5% copper/alloy. We can also provide 990 or 999 fine silver for custom orders upon request. All materials are tested with X-ray fluorescence (XRF) analyzers to guarantee purity.
We apply a multi-layer protective coating to prevent oxidation. This includes an initial anti-tarnish barrier layer, followed by a thick electroplating of Rhodium, 14K/18K Gold, or an electrophoretic lacquer (E-coating). This process extends the shelf-life and wear-resistance of our pieces.
Yes, we provide full custom jewelry box manufacturing. We design and print coated art paper boxes, pull-out drawers, velvet pouches, and luxury magnetic gift sets customized with your brand logo, offering a complete out-of-the-box product experience.
We enforce strict NDA (Non-Disclosure Agreement) protocols. Your 3D CAD files, molds, and designs are securely stored on private servers and are never shared, leased, or repurposed for other clients or platforms.
For OEM/ODM projects, CAD rendering takes 2-4 days. Once the CAD is approved, physical prototyping/sampling takes 5-7 days. Bulk production is typically completed in 10-15 business days depending on design complexity.
Absolutely. We regularly coordinate with global testing bureaus like SGS, Bureau Veritas, and Intertek. Clients can request random batch tests for lead, nickel, cadmium content, and gold plating thickness (micron testing).
We accept standard international payment methods, including T/T, L/C, Western Union, and secure online portals. Shipping is handled via Express couriers (DHL, FedEx, UPS, EMS) or air/ocean freight forwarding, depending on order volume.
Our standard plating thickness ranges from 0.03 to 0.1 microns (flash gold). However, for premium brands requiring heavy gold electroplating (Vermeil), we can apply 1.0 to 3.0 microns of 14K, 18K, or 24K gold.
