Released in 2012 as the lead single from Rihanna's album Unapologetic, Diamonds was written by Sia and built around a chorus repeating 'shine bright like a diamond'. The song topped charts around the world and became one of the defining pop anthems of the decade. Years later, that chorus detached from the song and became a standalone internet sound, dropped under videos of luxury hauls, proposal rings, glittering outfits and ironic broke jokes. Its staying power comes from the lyric itself, which doubles as a ready-made caption for anything shiny.
