CORO Jewelry: History, Identification, and Collectibility

CORO, derived from the first two letters of its founders' surnames—Cohn and Rosenberger—was a powerhouse of American costume jewelry from 1901 to 1979. Based in Providence, Rhode Island, the company became synonymous with high-quality, fashion-forward designs that mirrored—and often set—the trends of each era.

Design Legacy

CORO's catalog spanned Art Deco geometrics, Victorian revival filigree, whimsical figural pieces (animals, flowers, insects), and the sleek modernist lines of the 1950s and 60s. Their CoroCraft and Vendome lines represented higher-end tiers, using superior rhinestones, gold plating, and intricate construction.

Identifying Authentic CORO

Look for the CORO stamp, often in block letters, sometimes accompanied by "CoroCraft," "Vendome," or a copyright symbol. Early pieces may bear "Cohn & Rosenberger" or "CR." The mark confirms the piece was designed and manufactured by the company during its operational decades.
