Whether you are a designer launching a collection, a retailer stocking inventory, or someone commissioning a one-of-a-kind piece, the studio behind the work shapes the result. Expert jewelry CAD design is the digital foundation of modern jewelry making, turning sketches and references into precise 3D files built for casting and stone setting. The studios that do it best pair that digital skill with real bench craftsmanship, so a model does not just look good on screen; it holds up in metal. New York City, and the Diamond District in particular, is home to studios that do exactly this for designers and private clients alike. Here are seven of the best in 2026.
- CadCamNYC
CadCamNYC is a Manhattan studio with more than 20 years of experience and in-house CAD modeling, 3D printing, casting, setting, and finishing. For designers, it turns sketches into realistic 3D renders and full production; for retailers and private clients, it produces quality pieces with a fast turnaround from first model through polishing. Designers have relied on the studio for years to build their collections, and that same hands-on process now serves engaged couples and anyone wanting a custom piece, each with a personal job coordinator and a full quality-control team. The walk-in studio is located at 1156 6th Ave, Suite 305, in Manhattan.
Features:
- In-house CAD, modeling, casting, setting, and finishing under one roof
- 20+ years of fabrication and engineering expertise behind every piece
- Long-standing relationships with jewelry designers, plus a lifetime warranty
- Golden Casting
Golden Casting is a Diamond District workshop that helps designers, brands, and private clients turn concepts into finished jewelry. The studio builds 3D models engineered for casting and stone setting, not just presentation, and refines them with the client until the design is right. With CAD, printing, casting, setting, and finishing handled in-house, it manages the whole project so clients are not juggling separate vendors. Remote work is straightforward, and New York clients can visit the workshop.
Features:
- Production-ready CAD models built for manufacturing
- One team managing CAD through finishing
- Quality control from approval to final polish
- Tech-Designs NY
Located in the Diamond District, Tech-Designs NY is a full-service production partner with more than 30 years of experience. Its CAD designers build models engineered for manufacturing, then carry them through 3D printing, platinum and gold casting, setting, and finishing under one roof. The studio specializes in high-precision work other shops avoid, micropavé, thin shanks, and demanding platinum jobs, while keeping a designer’s files and client relationships their own.
Features:

- Couture Jewelry
Couture Jewelry is a family-run Diamond District atelier bringing master jewelers, CAD designers, and in-house casting under one roof.

Choosing the Right Partner
The right studio depends on what you are making. For a partner trusted by designers that extends the same in-house process to retailers and private clients, consider CadCamNYC, where CAD modeling, casting, and finishing all happen under one roof. For demanding platinum or micropavé work, Tech-Designs NY handles jobs other shops turn down, while Golden Casting suits brands wanting one team from concept to finished piece. For a custom engagement ring with a hands-on atelier feel, Couture Jewelry stands out, and Sarkissian or 3DM suit designers who mainly need expert modeling. Whichever you choose, ask whether files are built to cast, how revisions are handled, and whether fabrication happens in-house. For dependable jewelry CAD design backed by real production capability, any studio here is a solid starting point.
