Diamonds was released by Rihanna in 2012 as the lead single from her album Unapologetic and became a worldwide number one hit. Written in part by Sia, the song stood out for its hopeful, euphoric tone compared with Rihanna's darker earlier singles. Its chorus has since become shorthand online for anything precious, beautiful or glowing, which is why short clips of the hook keep circulating in edits, memes and fan videos celebrating luxury, confidence and standout moments years after the original release first topped charts globally.
