From June 1 to 4, the Las Vegas Estate Jewelry & Watch pavilion will give JCK showgoers access to a promising retail category

JCK Las Vegas is, first and foremost, a place to buy new merchandise. This year, however, the debut of the Las Vegas Estate Jewelry & Watch pavilion, on the Bayside level of the Mandalay Bay Convention Center, gives retailers the chance to sell or trade jewels, too.

“It’s almost like another amenity to JCK,” says Scott Diament, president and CEO of the Palm Beach Show Group, organizer of the new pavilion. “You could go to an exhibitor in the estate section saying, ‘I have a Kashmir sapphire to sell.’ ”

That’s just one perk of the estate section, which houses nearly 30 exhibitors, including Miami-based Vivid Diamonds & Jewelry; Los Angeles’ Jogani, a specialist in pieces from the 1910s, ’20s, and ’30s; and Provident Jewelry, the West Palm Beach, Fla.–based ­retail and wholesale business of which Diament is an owner (his retail roots help explain why he remains a passionate advocate for the category).

“We have found at Provident that mixing new and repeatable goods, branded with estate, allows us to ride out any of the downturns in the market or any of the difficulties in the current environment due to stratification,” Diament says. “This allows us to pivot wherever the market is going.”
