Where to eat, drink, and blow off steam between all the jewelry-buying at October’s LUXURY and JIS showsSo you’re planning six gorgeous days in Miami for the inaugural JCK LUXURY Miami show—Oct. 14–16 (the first day is invite-only, the last two are open to all registered buyers)—which conveniently overlaps with the always-anticipated JIS Miami show, Oct. 15–18, now in its first year under the JCK umbrella.
