Custom Jewelry Manufacturing for Independent Brands
Brrin Jewelry is a lab-grown diamond jewelry OEM/ODM manufacturer based in Panyu, Guangzhou, supporting independent jewelry brands, designers, wholesalers and custom jewelry businesses with sample development and flexible small-batch production.
We combine jewelry manufacturing with direct lab-grown diamond sourcing, including center stones, fancy shapes, matched pairs and calibrated melee. Clients can send a reference image, sketch, CAD file, technical drawing or existing sample, and we support projects from diamond selection and CAD development through casting, setting, polishing, quality control and finished jewelry production.
We are best suited to custom and design-driven projects rather than large-volume standard jewelry. MOQ and production quantity are evaluated according to the design, metal, stone requirements and manufacturing complexity.
What We Manufacture
We manufacture custom fine jewelry including:
• Engagement rings and wedding rings
• Custom ring settings and semi-mounts
• Lab-grown diamond jewelry
• Tennis bracelets and tennis necklaces
• Earrings and diamond studs
• Fancy-shape diamond jewelry

Projects can be produced in 14K or 18K gold, platinum and selected silver designs depending on the product requirements.
OEM & ODM Jewelry Manufacturing
We work with both client-supplied designs and new product development projects.
You can send us:
• Reference images
• Sketches
• CAD files
• Technical drawings
• Existing jewelry samples
• Product specifications
Our team reviews the construction, materials, stone requirements and production feasibility before quotation and sampling.
Small-Batch Jewelry Production
For independent brands and growing jewelry businesses, ordering large quantities for every new design can create unnecessary inventory risk.
Brrin Jewelry supports sample development and small-batch manufacturing, allowing brands to test new designs before moving into repeat production.
Production quantities and MOQ depend on the design, materials and manufacturing requirements.
Lab-Grown Diamond Sourcing for Jewelry Projects
In addition to jewelry manufacturing, Brrin Jewelry provides lab-grown diamond sourcing for custom jewelry projects.
We can source center stones, fancy shapes, matched pairs and calibrated melee according to the design, dimensions, color, clarity and target budget.
Available options include round, oval, emerald, pear, radiant, cushion, marquise and other fancy shapes, including larger-carat stones for engagement rings and custom jewelry.
For projects requiring certification, IGI-certified lab-grown diamonds can also be sourced based on the required specifications.
Combining diamond sourcing with manufacturing helps brands manage stone selection, setting compatibility, cost and production through one supplier.
Lab-Grown Diamond Jewelry Manufacturing
We provide lab-grown diamond sourcing together with jewelry manufacturing.
Available options include round and fancy-shape lab-grown diamonds for engagement rings, earrings, tennis jewelry and custom designs.
For projects that already have diamonds selected, we can also manufacture the setting based on the confirmed stone dimensions and specifications.
