The Chainsmokers and Halsey are ending the summer on a high note, marking the occasion with their hit "Closer" attaining diamond status. For a song to be certified diamond by the Recording Industry Association of America (RIAA), it has to reach sales (and streaming equivalent sales) of 10 million units.
The duo and the singer both shared the news on Instagram Saturday afternoon (Sept. 15) with photos of their diamond plaques.
