The Chainsmokers and Halsey are ending the summer on a high note by celebrating their 2016 Columbia Records hit “Closer” attaining diamond certification. That status is marked by the sales (and/or streaming equivalent) of 10 million units and is awarded by the RIAA.

The duo and singer both shared the news on Instagram Saturday afternoon (September 15th) with photos of their diamond plaques. The Chainsmokers wrote: “CLOSER is officially DIAMOND in the U.S. !!” Halsey posted, “Been on tour for a hundred years so I haven’t even gotten home yet to unwrap this baby. CLOSER IS CERTIFIED DIAMOND! 10 times platinum! TEN MILLION!”
