The 2012 JCK Las Vegas show will highlight 338 manufacturers and designers whose products are made exclusively in the United States.

More than 50 new exhibitors will showcase their American-made jewelry at this year’s event. The event will distinguish between U.S.-made products through the show guide, online map, booth signs, and American flag decals.

“We actually began identifying manufacturers and designers who produce solely in the United States last year and received very encouraging feedback on the program,” Yancy Weinrich, industry vice president of JCK Events, said in a statement. “Many retailers shared how important this feature is, as they have seen the hallmark of ‘Made in the U.S.A.’ positively influence consumer purchases over the last few years.”
