Gearing up for the LUXURY, JCK Las Vegas, and Swiss Watch shows The most important market season in the American jewelry industry is fast approaching. And if the upbeat mood that has characterized the show circuit this year is any indication, then exhibitors at the JCK shows in Las Vegas should prepare for robust trading.First on the calendar (May 29–June 4) is LUXURY and its sister event, Elite Enclave, at the Mandalay Bay Hotel & Casino. Right on their heels are the JCK show and Swiss Watch, at the same location from June 1–4.Now in their second year at Mandalay Bay, the shows aim to offer the widest selection of products in one location. (More than 2,500 firms from 22 countries participate.) Two affiliated events—the Equipment, Technology and Supplies (ETS) pavilion and the AGTA GemFair—benefit from extended dates; they run from May 31–June 4.Revelers are in for a treat.
