Custom Jewelry Manufacturing from CAD or Reference Image

Have a jewelry design, CAD file, sketch or reference image?

Brrin Jewelry provides custom lab-grown diamond jewelry manufacturing for brands, designers, wholesalers and trade clients. We can develop your design from an existing CAD file, technical drawing, sketch or reference image and support the project through production.

Start with Your Design

You can send us:

  • CAD or 3D design files

  • Technical drawings

  • Hand sketches

  • Reference images

  • Existing jewelry samples

  • Basic product specifications

If the design is not production-ready, our CAD team can help adjust the structure, stone layout and manufacturing details before production.

From CAD to Finished Jewelry

Our production process can include:

Design Review → CAD Development → Diamond Sourcing → Stone Matching → Casting → Setting → Polishing → QC → Delivery

  • Fancy-shape diamond jewelry

  • Large-carat jewelry
