Historical note:

            Coro, Inc. was an importer, exporter, and seller of costume jewelry and simulated pearls, conducting business worldwide. The company was founded as the partnership Cohn & Rosenberger in New York in 1902. The partners incorporated in New York in 1913 and adopted the corporate name Coro, Inc. in 1943. During World War II, Coro, Inc. operated partially as a prime contractor for the federal government, manufacturing insignia, parts for bomb nose fuses and base detonator fuses, and "miscellaneous items". It also manufactured as a subcontractor under another prime contractor during the war years. As of the mid-1940s, the parent company in New York was operating subsidiaries, showrooms, and/or plants in Providence, New York, Chicago, Los Angeles, San Francisco, Miami, Toronto, and London, England. Letterhead used for correspondence in the 1950s indicates additional offices in Dallas and Atlanta.

            The subsidiary Cohn & Rosenberger, Inc. of Rhode Island was established in 1910 in Providence. The first operating facility was located on Chestnut Street. Some time before 1946 a manufacturing operation existed at 183 Public Street. In 1929, the company moved its factory, stock and shipping facility to a larger building at 167 Point Street. Operations continued in this building until the company's closure in 1979; the Coro Building is still a Providence landmark and today houses Harvard Health. During the 1950s and '60s, Coro, Inc. of Rhode Island was the largest manufacturer of costume jewelry in Providence and had a national, if not international, reputation. By the mid-1960s additional plants were operating in Olneyville and Bristol.

            In 1970, the company became a subsidiary of Richton International Corporation. Richton closed Coro's Point Street location in 1979. Listings for Coro, Inc., "jewelry manufacturers", in the Providence City Directories end in 1977. Interestingly, after this point there are listings for "Coro Federal Credit Union" at the same location. Finer details regarding the scope of business conducted by Coro, Inc. and its subsidiaries up to the mid 1940s can be obtained by reading Securities and Exchange Commission Form S-1 registration, 1946, listed in the inventory below.

Scope and content:

            The entire collection is comprised of financial records. Correspondence exists in a very small amount and always relates to the records with which it is filed. The account books in the collection are journals, ledgers, disbursements, receipts, loans, and purchases (domestic and foreign) for the parent company, located in New York, and some of its subsidiaries, located in Rhode Island, Canada, and London. Accounts listed in these books include such details as materials used in the manufacture of the company's product, overhead costs, profits and loss, names of individuals such as owners and employees, and names of other companies with which Coro, Inc. and its subsidiaries conducted trade. The boxed records include balance sheets, financial statements, profit and loss statements, and Securities & Exchange Commission filings for varied locations including Rhode Island, New York, Canada, London, and various subsidiaries whose geographical locations are unknown.

            A 1946 stock prospectus includes a history of the company up to that point and a breakdown of the locations and origins of subsidiaries existing at that time.

Processing note:

            Initial sorting and labeling of the boxed files, done by Cindy Bendroth in 1991, facilitated final processing of the records. In 1998, these files were organized by company/subsidiary and then further arranged by type of record and chronology. Processing of the account books required determining the type of records within and to which company/subsidiary they belonged, and labeling them accordingly. Several photostat ledger sheets (Coro RI and Coro Canada, Ltd.) that were deteriorating and/or fading were photocopied for patron use and preservation purposes.
