The firm of Cohn and Rosenberger was established in 1901 by Emanuel Cohn and Carl Rosenberger, Later incorporated in 1943, they shortened the name to Coro, Inc., combining the first two letters of the two rounders last names. Founded as an accessories boutique in New York City, Cohn and Rosenberger were businessmen who focused on business operations and growth, but they nevertheless had a good eye for the arts, hiring very talented professional jewelry designers who were allowed to develop their own creative visions at Coro. Even manufacturing was outsourced until they finally purchased their own facility in Providence, Rhode Island in 1929. The company also expanded overseas, establishing the Corocraft brand in England in 1933 and moving into Canada soon thereafter, and they soon had design stores in most major American cities. Coro designs tend to be feminine and graceful even on the larger, heavier, earlier items. The company made a wide variety of pieces from figural to floral, and they developed different lines marketed at different price ranges but always with recognizable quality. Coro ceased ongoing operations in the U. S. in 1979 and continued producing jewelry in Canada until the mid 1990s.
