• Coro, Inc., one of the largest and most prolific costume jewelry manufacturing and wholesale companies in the United States and the world, would have been 100 years old in 2001, had it only lasted that long.

  • The Beginnings:
  • Coro was begun in 1901 by Emanuel Cohn and Carl Rosenberger who opened a small accessories store on Broadway in New York City. Not until 1943, did the company name  Coro, a contraction of the first two letters of each partner's last name, change to Coro, Inc.

  • But Cohn and Rosenberger were not designers of jewelry. They may have had their own ideas of what they envisioned and how they wanted to sell their jewelry but they did not individually or together design any of it; they found professional jewelry designers for this work. Cohn & Rosenberger was first a sales organization, later to acquire its own manufacturing facilities.
