Reed Exhibitions, which produces the JCK Show and associated events, will assume management of JCK magazine and JCKonline.com, the company announced. The two groups previously had been in separate divisions under parent company Reed Elsevier.

"JCK has more than a century of history in the jewelry industry, and the brand is among the strongest in the world," Reed Expo Americas president Chet Burchett said in a statement. "Bringing the magazine into the broader JCK portfolio makes it easier to create greater value for our customers. It streamlines relationships and accelerates innovation and development of the brand."

Group vice president Dave Bonaparte will assume management responsibility for JCK magazine.

"We have always had an excellent relationship with JCK magazine, and we are excited about the potential to create new value and increasingly effective programs for our customers," said Nancy Walsh, executive vice president, Reed Exhibitions, North America.
