Attendance at JCK Las Vegas 2012 increased 21 percent over two years, according to show organizer Reed Exhibitions.

The show, held at the Mandalay Bay Convention Center, featured new improvements and amenities including mobile maps, spa treatments, Kosher food options, and entertainment.

This year, JCK welcomed exhibitors from 22 countries, including Australia, Brazil, China, India, Malaysia, Mexico and Russia. The LUXURY, Elite Enclave, and Swiss Watch shows proved successful with the international attendees, attracting 850 high-end and global retail stores, show organizers said.

JCK also entertained more than 4,000 buyers and exhibitors at the “JCK Rocks the Beach” party at Mandalay Bay, featuring hit band OneRepublic.

“I couldn’t be happier with my JCK experience this year,” Mark Moeller of RF Moeller Jeweler in Minneapolis, said in a statement. “There is no other show that allows us to gauge the future for new ideas and products than JCK.”
