Top 5 NYC Custom Jewelry Studios Offering In-House Jewelry CAD Services

If you are having a piece made, whether it is an engagement ring, a redesign of an heirloom, or something entirely your own, the studio you choose matters as much as the design. The best results tend to come from places that handle the whole process themselves rather than passing your project between outside vendors. When a studio keeps its modeling, printing, casting, and finishing under one roof, you get tighter quality, a clearer line of communication, and a piece that turns out the way you pictured it. Every handoff to an outside shop is a chance for a detail to shift or a timeline to slip.

That is why in-house capability is worth looking for. A studio that runs its own CAD and modeling controls the design from the first digital file onward, and pairing that with real bench craftsmanship is what separates a memorable custom piece from an average one. Here are five NYC studios that bring design and fabrication together under one roof in 2026.

1. CadCamNYC

CadCamNYC is a full-service custom jewelry studio in Manhattan with more than 20 years of experience. Design, CAD modeling, 3D printing, casting, stone setting, and finishing all happen in-house, so the same team sees your piece from first sketch to final polish. Its walk-in studio lets you sit down with a specialist, review a realistic 3D model, and request as many revisions as you need before anything is cast. Because every stage stays in the building, the approved digital model carries straight into the finished piece, with the same team accountable throughout. Designers have trusted CadCamNYC for years to build their collections, and private clients now get that same studio-grade craftsmanship, whether the project is a single ring or a full line.

Best known for:

• A walk-in Manhattan studio with in-person, hands-on consultations
• Everything handled in-house, from CAD modeling through finishing
• A lifetime warranty covering checkups, polishing, wear and tear, and sizing

2. ROEN Bespoke

ROEN Bespoke is a New York atelier focused on custom engagement rings and fine jewelry, handcrafted by master jewelers in its NYC studio. Clients work through natural diamonds, rare gemstones, and antique stones, and follow the build through a private online portal that shows stone selection, CAD renderings, and design milestones in one place. That transparency, paired with hands-on crafting and polishing in the studio, makes ROEN a strong fit for clients who want to stay close to every stage.

Best known for:

• Bespoke engagement rings crafted by master jewelers
• A client portal for tracking CAD renderings and milestones
• A specialty in natural, rare, and antique stones

3. Couture Jewelry

Couture Jewelry is a family-run Diamond District atelier that brings master jewelers, CAD designers, and in-house metal casting together under one roof. Every engagement ring begins with a private consultation, moves through 3D CAD renderings and a wax model you can try on, and is then cast, set, and finished by bench jewelers on 47th Street. The studio works in natural and lab-grown diamonds, all GIA-certified, and guarantees its workmanship for the life of the piece.

Best known for:

• A one-on-one atelier experience with master bench jewelers
• CAD renderings and wax try-on models before casting
• In-house casting and hand-setting in Manhattan

4. Saray Jewelry

Founded by a master jeweler in 1982 and now run with his son, Saray Jewelry is a high-end production house in the Diamond District where all design and production happen in-house. The team blends traditional metalsmithing, including hand-forged platinum, with 3D CAD development, so a consultation is grounded in real fabrication knowledge. Known for bespoke engagement rings and wedding bands built from the ground up, Saray serves private clients as well as some of the most established jewelry houses in the country.

Best known for:

• More than 40 years of hands-on jewelry-making experience
• In-house design, CAD development, and advanced platinum metalsmithing
• Bespoke engagement rings and heirloom reconstruction

5. Marisa Perry Atelier

Marisa Perry provides custom jewelry design out of NYC, building each piece around the client's own stone. The team scans the stone for exact measurements, produces a 3D CAD rendering for approval, then casts the model and completes the workmanship by hand, including micropavé setting done under a microscope. That mix of precise digital modeling and hand finishing suits clients who want a highly personal piece.

Best known for:

• Custom design built around your own diamond or gemstone
• Scan-to-CAD accuracy with a rendering to approve
• Hand-finished micropavé setting

Choosing the Right Studio

The right studio depends on what you are after. For a brand trusted by designers that extends the same studio-grade process to private clients, consider CadCamNYC, where design, CAD modeling, casting, and finishing stay in-house from first sketch to final polish. If decades of traditional metalsmithing matter most, Saray Jewelry brings more than 40 years of hand-forged expertise. For a one-on-one atelier experience with try-on wax models, Couture Jewelry is a strong fit, while ROEN Bespoke suits clients who want full visibility into every milestone through a private portal. And for a piece built entirely around your own stone, Marisa Perry provides precise scan-to-CAD design finished by hand. Whichever you choose, the common thread is control of the process, so ask how revisions are handled and whether casting and finishing happen on-site.
