Industry Snapshot
Key metrics for the jewelry and silverware manufacturing industry.
Industry Definition & Overview
Jewelry and Silverware Manufacturing (NAICS 339910) encompasses establishments primarily engaged in manufacturing jewelry from precious metals, precious and semiprecious stones, or base metals clad with precious metals. This industry also includes manufacturers of costume jewelry, silverware, hollowware, and flatware made from precious or nonprecious metals. Gem cutting and polishing operations fall within this classification as well. The U.S. Census Bureau[5] groups these producers within miscellaneous manufacturing.
Production methods range from traditional hand fabrication in small artisan workshops to high-volume casting and stamping operations. Precious metal jewelry manufacturing requires skilled goldsmiths and gem setters working with gold, silver, platinum, and palladium. Stone setting demands expertise in prong, bezel, channel, and pave techniques. Costume jewelry production relies on base metal casting, electroplating, and assembly-line methods. Silverware manufacturers produce flatware, serving pieces, and decorative hollowware through stamping, spinning, and hand-finishing processes. The Bureau of Labor Statistics[6] tracks jewelers and precious stone workers as a distinct occupational category.
Under SBA size standards[7], NAICS 339910 carries a threshold of 700 employees. New York City's diamond district and Providence, Rhode Island remain historic production centers, though manufacturing has dispersed to other regions. Import competition from low-cost producers in Asia pressures domestic manufacturers on price-sensitive product lines. Custom and high-end artisan jewelry commands premium pricing and sustains many small domestic workshops. Raw material costs fluctuate with precious metal commodity markets, creating margin volatility for producers.
