Karu Arke Inc costume jewelry
New York City based costume jewelry manufacturer Karu was the successful collaboration of Paul Kaufman and Jack Ruderman, which began in the 1940’s. Karu jewelry was extremely popular. According to Jack Ruderman, the treasurer of Karu, their sales already in 1948 amounted to about $ 22 million. Traditionally, sales of costume jewelry on Christmas Eve were very high. The quality and designs of Karu costume jewelry are similar to Weiss or Weisner.
Noteworthy, the then-famous jewelry company Coro, owned by Cohen & (and) Rosenberger, filed a complaint against Karu in 1952. In particular, due to the similarity of the names of the two companies – Caro and Karu. However, the court considering this case did not find sufficient grounds to satisfy the claim. Indeed, Karu meant the fusion of the first two letters of Kaufman-Ruderman. However, Karu’s name soon changed to Karu Arke Inc. Also, among Karu trademarks was Karu Fifth Avenue.
By 1972, the company ceased to exist. Thus, all Karu brand products are vintage and collectible.
