Part II of my series on top vintage costume jewelry brands, featuring Coro.
Cohn had died in 1910, but the Rosenberger family still gave tribute to his contributions to the brand. Carl continued to manage the company until his death in 1957, when the brand was taken over by Gerald Rosenberger, Carl's son, who managed the company until his death 10 years later.
The family sold 51% of the company to Richton, Intl., who bought out the whole company in 1970. In 1979 Coro went bankrupt and closed it's doors for good.
