What Does the C.R. Stand for in Vintage Jewelry?


When costume jewelry features a maker's mark, it is considered a signed piece. A symbol or script appears on a clasp or in another inconspicuous place. If a "CR" mark is found, the piece is an early example of a product from the prolific Coro Jewelry Company.


  • The CR mark appears as CR or C and R, and stands for Cohn & Rosenberger, the earliest incarnation of Coro. The imprint features a large capital C with a capital letter R in a slightly smaller pica size resting at its side. If the mark appears as "C and R," the word "and" bisects the letter C.

Early History


  • From the onset, the company featured imported costume jewelry pieces, mixed with work from a stable of designers who developed original work and adapted popular styles.


  • The widely recognized Coro name appeared on jewelry concurrently with other marks, but was officially adopted in 1947, when the company name was officially changed to Coro.
