Uncas Manufacturing Co., once known as America’s largest manufacturer of rings, is celebrating the 90th anniversary of the founding of the Rhode Island-based company. Uncas offers full-service capabilities from concept development to finished product to shipping for all channels of distribution including direct mail catalogs, major department stores, retail chains, television networks, and other jewelry manufacturers.

In 1998, the company acquired another Providence-based firm, Vargas Manufacturing Co., a high-tech manufacturer of fine and costume jewelry. Uncas then moved to a modern one-level, 100,000-sq.-ft. facility that features a 5,000-sq.-ft. plating area—one of the largest in-house plating rooms in Rhode Island. The company also uses a CAD system and computer imaging equipment. Its products include specialty items such as hair ornaments, earrings, bracelets, rings, necklaces, pins, charms, and custom-made gifts.
