New York City’s Diamond Dealers Club (11 W. 47th St.) will host a free evening of networking on Tuesday, May 21, from 7 p.m. to 9 p.m.

The “Hot Rocks and Heavy Metal” event—which caps off the 12-day NYCxDESIGN celebration—gives the public a chance to mingle with artisans, educators, manufacturers, and casters. It is organized by the New York City Economic Development Corp., the 47th Street BID, and silversmith CJ Recht.

Registration through Eventbrite is required, and refreshments and hors d’oeuvres will be served.
