Zoë Kravitz's engagement ring from Harry Styles is one hell of a ROCK, y'all! As you know, the couple got engaged pretty quickly after dating for only around eight months, but that doesn't mean Harry didn't put in the work to get her a fabulous diamond! According to what Ajay Anand, CEO of Rare Carat, told PageSix on Monday, the diamond is likely 10 to 12 carats. That many carats can be worth roughly $800,000 - and that's for JUST the one stone! The "seriously huge" diamond, per Anand, looks to be an elongated cushion-cut rock set in a yellow gold bezel.
