Kozza & Company

Kozza & Company operates in the precision-driven world of jewelry manufacturing, where craftsmanship meets inventory control and prototypes take shape behind closed doors. Designers and retailers rely on firms like this to bridge creative concepts with producible pieces, often involving sampling runs, material sourcing, and small-batch testing before scaling up. Production stages blend CAD rendering with hand-finishing, and compliance checks ensure every order matches specifications before leaving the facility.

Find the workshop tucked inside the garment district’s upper floors — 226 W 37th St 8th Floor, New York, NY 10018 — a building shared by designers and manufacturers who keep the neighborhood alive with samples and sketches. The area’s vertical layout suits businesses that need discrete spaces without the storefront foot traffic, and the location fits anyone shuttling between showrooms and production sites. Elevators handle the heavy lifting; everything else stays inside.

The team can usually be reached at (212) 613-0000 to discuss orders or confirm drop-offs. Reach them directly or use the map to plot a route that avoids street closures around Penn Station. That building never sleeps; neither does this workshop.
