Coro Jewelry, long a stalwart of the United States Jewelry business started in 1901 and closed its doors in 1979. The name came from a combination of names of the two partners who started the business. Mr. Cohen and Mr. Rosenberg incorporated the business in 1943. Mr. Rosenberg and Mr. Cohen hired artists to design the jewelry and hired manufacturers to manufacture the jewelry. They relied on their business acumen to operate the business and sell merchandise.
In 1945 (according to this mark) the Coro company introduced this set of jewelry. Adorned with rhinestones and twisted ropes on what appears to be fancy fans , this jewelry is a little busy for my tastes. However, Coro has reached new popularity amongst collectors, and the original box is part of this package. The pieces have not been worn much and they are in excellent condition. The broach is 1 and 3/8 inches in diameter and has a safety clasp, and the earrings are screw backs.
