MC Production US LLC

MC Production US LLC operates out of a small industrial floor on West 48th Street, turning raw concepts into delicate final pieces. Jewelry design and fabrication run through the same benches, and prototypes evolve from sketches to wax models without leaving the building. Most pieces begin with pattern-making and CAD modeling before casting or 3D printing takes over. Finishing crews apply their tools to polish, engrave, and set any stone you can name. Even quality testing happens on-site under controlled conditions that stay within industry parameters. Shipments leave the same door they entered after inspection, heading to stores or straight to clients.

This 42 W 48th St Suite 602 location puts the team above 5th Avenue’s steady foot traffic. The corridor’s mix of diamond merchants and garment lofts keeps suppliers and collaborators within a single subway stop. When visitors drop by for in-person consultations, they step into a building that has housed creative trades for decades. Elevator banks echo with deliveries to neighboring jewelry studios and law firms alike. Late afternoon light catches the windows as the day winds down, signaling another shift of production wrapping up for the night.
