Professional jewelry CAD design in NYC’s Diamond District

CAD DESIGN

Production-ready CAD for established trade clients, with defined specifications and an agreed manufacturing scope.

JEWELRY CAD DESIGN

Our CAD work is reserved for existing trade clients with defined project requirements. Please provide dimensions, stone measurements or scans, metal specifications, setting details, reference materials, and the intended manufacturing process.

We develop clean geometry and production-minded models with attention to tolerances, stone fit, assembly, and finishing requirements. Renderings support client review before manufacturing approval.

Scope, revisions, pricing, and timing are agreed before work begins. We do not offer introductory jewelry-business guidance or new collection-development services.

Over 30 Years of Jewelry Design & CAD Expertise.

Manufacturing-Minded Detail

Careful attention to geometry, surfaces, stone placement, and construction supports the quality of the finished piece. CAD decisions reflect the practical requirements of casting, setting, assembly, and finishing.

Defined Technical Workflow

Existing clients submit a technical brief and reference materials by email. We confirm the agreed scope and production requirements, prepare models for review, and proceed after approval.

Precision in Design

Jewelry 3D Modelling provides a level of precision that is difficult to achieve with hand-drawn sketches. The advanced software we use allows us to incorporate exact measurements, ensuring your design is accurately represented. This precision minimizes surprises when your design is transformed into a physical piece, offering a seamless transition from concept to creation.

Testimonials

★★★★★

I met with Carlos to talk about a project in silver. the pieces are something that would be nearly impossible to make molds for so I needed to print 3D wax. He was understanding, knowledgeable, and accommodating. His craftsmanship is like no other in NYC's jewelry district. The castings are gorgeous. Your project is in good hands with Carlos and Tech-Designs.

For the people who reads this review and need a honest opinion regarding Tech Design I can say one thing, just this year alone Carlos did over 20 projects for us in witch we generated over 3 million in purchase orders. His CAD skills are at the highest level of jewelry manufacturing and because he is a jeweler and designer he makes everything work flawlessly. I would definitely recommend Carlos and Tech Designs.
