Coro, Corocraft, Coro Duette

Coro, Corocraft and Coro Duettes. Corocraft, founded in 1901 by Emanuel Cohn and Carl Rosenberger, enjoyed great growth and success which may be due to a large extent to the skills of their chief designer, Adolph Katz. After the second World War, Coro became the largest costume jewelry manufacturer in the world, producing a bewildering range of jewels designed by an army of designers under the coordination of the chief designer. Over 50 trademarks were issued to Corocraft including one of the most collectible marks ‘Duette’ which was applied to pieces in which two or more dress clips were mounted upon a frame so that they could be worn individually or together as a single pin.
