Cohn & Rosenberger (CORO)

The name Coro is a contraction of an earlier trade name COHN & ROSENBERGER and they've been in business since 1902. During the 1930's and the great depression, Coro built a huge plant in Providence, RI and after WWII found itself very profitable and surged ahead of the competition. In the 1940's, the highest price line of jewelry Coro produced was under the name COROCRAFT and they offset that with less expensive jewelry that could be found in 5 and dime stores. Adolph Katz was the master of the movable jewelry that Coro produced. His jewelry moved, it quivered on springs, etc. and it was very well made. Katz also designed crowns with multi-colored rhinestones in honor of the wedding of Princess Elizabeth of England. Katz was also a fine businessman and helped run the Coro factory.
