You probably don't know that Sia had a hand in Rihanna's hit 2012 song “Diamonds.” The song served as her lead single off the album Unapologetic. The song was so successful that a little more than a year after it's release, it was certified quadruple Platinum in the United States by the RIAA. It had even more success in Sia's native Australia with the ARIA certifying it 5X Platinum in 2013.

Sia wrote the song along with American rapper Benny Blanco and the Norwegian production duo known as StarGate. Benny Blanco explained in a 2012 interview with The Source magazine that both he and StarGate wrote the beat to the song but it wasn't until Sia came into the writing process that the song we know came together. They sent Rihanna the song while she was in London on tour and she was immediately interested. Blanco explained to The Source, “She [was] flippin' out. She played it like seven times in a row. It's her favorite song [for the new album.]” The most amazing part of the story is that Sia wrote the song in only fourteen minutes.
