Explore a selection of our premium custom models engineered for international jewelers, wholesalers, and e-commerce brands.
In the contemporary jewelry industry, sourcing high-end gemstone earrings is no longer merely a transaction based on aesthetic merit. It demands strict structural integrity, micro-level stone-setting precision, ethical gemstone sourcing, and absolute supply chain transparency. As search engines transition to semantic search, user intent has migrated toward seeking suppliers who combine traditional handcrafted artistry with industrial-grade technological systems.
Compliance with strict chemical guidelines, ensuring raw materials such as Brass, 925 Sterling Silver, and K-Gold are free from lead, nickel, and cadmium. We employ professional XRF alloy testing instruments to certify alloy purities before casting.
Shorter consumer cycles require rapid-prototyping capabilities. With 3D CAD modeling and digital printing, concepts transform into physical samples within 72 hours, allowing brands to respond dynamically to viral trends.
Enterprise sourcing departments require suppliers with verified BSCI, SGS, and ISO certifications. Transparency in mineral sourcing, lab-grown diamonds, and sustainable factory operations is critical for global brand equity.
Founded in 2009, Locke Jewelry is a premier OEM/ODM manufacturer specializing in premium gemstone jewelry based in Panyu, Guangzhou.

Over 60% of high-end jewelry globally is processed through Panyu. Our strategic location offers unparalleled competitive advantages.
Guangzhou Panyu houses thousands of specialized gem cutting, metal refining, plating, and micro-setting workshops. This cluster density allows Locke Jewelry to source rare gemstones, customized alloys, and specialized tools within hours. By reducing transit times and logistics overhead, we pass substantial cost savings and accelerated production timelines directly to our global client base.
Jewelry making is a generational trade in Panyu. Our workforce of 500+ master craftsmen possesses micro-setting and hand-finishing skills that cannot be replicated by automated machines alone. This expertise ensures every claw setting, bezel edge, and hinge design on your gemstone earrings is structurally resilient, smooth to the touch, and optimized for maximum light dispersion.
Panyu features strictly monitored, ecologically compliant electroplating zones. This enables us to provide advanced chemical vapor deposition (CVD) and physical vapor deposition (PVD) finishes, offering thick 14K/18K gold layers, rhodium, and anti-tarnish protective coatings that meet strict global REACH regulations.
Through optimized production protocols, centralized purchasing of high-purity silver/gold grain, and semi-automated processing, Locke Jewelry minimizes raw material waste. This efficiency yields highly competitive unit pricing, helping premium retail brands maintain strong gross margins.
We tailor our gemstone earring formulations and manufacturing specs to match specific regional demographics and sales networks.
