Rihanna's "Diamonds" music video is not very sparkly — it's  downright dark! The singer debuted the nearly-5-minute video on Thursday, and in  it, she broods throughout a myriad of backdrops. "Diamonds" begins with Rihanna  rolling a joint filled with the gems, and then smoking before a quick visual of  her hand being ripped from a tattooed man's hand ... obviously a nod to Chris Brown. She's then shown running in the darkness from a  bright light before ending up in the wild with two horses (one is lame and lying  on the ground until the other helps it up and they run off together). At the end  of the video, Rihanna wanders through an apocalyptical scene with dirt on her  face as a man on fire walks calmly through the melee.

Although the  single off her November 19 seventh album, Unapologetic, has not  been the most well-received by fans because of its simple lyrics and monotonous  chorus, Rihanna says it has special meaning to her. "It was the right powerful  record," she tells MTV. "It was hopeful. It was also different from what people  are used to hearing from me. It was a song that meant something, and that's the  whole theme throughout the album."
