SHOWS For years, attendees of jewelry market week in Las Vegas have had to sacrifice Memorial Day to travel. Next year, however, they’ll be free to enjoy the holiday. The invite-only LUXURY show will start Friday, June 2, and run through Sunday, June 4. LUXURY opens to all JCK badge holders on the same day that JCK kicks off, Monday, June 5; both shows conclude Thursday, June 8. “We recognize and are sensitive to the several hundred companies across LUXURY and JCK that observe these holidays,” explains Reed Jewelry Group senior vice president Yancy Weinrich. Be sure to check the schedule for other jewelry events happening during 2017 market week.
