Technically, Sia isn't covering RiRi's song, because the We Are Born singer actually penned the song along with producer Benny Blanco. 

Writing a number one hit isn't easy and neither is performing it, but Sia sings "Diamonds" with just as much fervor as RiRi.

Putting her own spin on the track, Sia's interpretation of "Diamonds" has a prominent bubbling energy, unlike RiRi's semi-melancholy version.
