Barring a force majeure, such as last year’s Hurricane Irma, Reed Exhibitions’ Jewelers International Showcase (JIS) October will return to its longtime home at the Miami Beach Convention Center on Oct. 19, with a raft of buyer-focused additions, updates, and enhancements.

“Reed has invested millions of dollars in the JIS brand across the board, from signage to amenities, with the goal of all those components and partnerships that got developed coming together for the first time this October,” says Jordan Tuchband, industry vice president of JIS Events.

In an unprecedented step, JIS will take over the entire convention center, fresh from its $620 million renovation. The bigger space will allow the four-day show to co-locate with ­another Florida mainstay, the Centurion South Beach show, which is bringing nearly 100 luxury brands, including a new ­pavilion of Forevermark suppliers, to the event. ­Attendees will be able to shop both shows with one badge, “making it easier for everybody,” Tuchband says.

On top of Centurion’s arrival, “the Italian Pavilion is 50 percent larger than last year,” Tuchband continues. “The upscale Galleria Pavilion is 40 percent larger, and there’s been an ­increase in new companies and ­returning companies that had stopped doing the show. There are going to literally be hundreds of brands that will be new compared to a year ago.”

Another neighborhood making its debut in October is the Equipment, Technology, and Services Pavilion, which is based on the ETS section at JCK Las Vegas and features some 25 exhibitors marketing everything from software to lasers to safes. “It’s a mixture of some new vendors and some that were already at the show but were randomly scattered,” Tuchband says.

Overall, JIS October, the ­second-largest jewelry show in North America after JCK Las Vegas, is poised to be one of the year’s blockbuster events, Tuchband says. Between longtime exhibitors such as Royal Chain (currently celebrating its 40th anniversary), Shy Creation, and Siera Jewelry and a host of ­newcomers—including Ippolita, Le Vian, and Shinola—that are showing under the banner of Miami-based Demir Group International, a sales and marketing agency specializing in the Caribbean and duty-free markets, the show “is worth checking out,” he adds. That’s putting it mildly!
