Last week Kanye West proposed to Kim Kardashian on her 33rd birthday in a huge way, and we finally have a better view of her gorgeous ring. Over the weekend the reality star continued her birthday celebration at TAO at The Venetian in Las Vegas, where we got a closer look at her truly stunning rock. Kim's Lorraine Schwartz-designed engagement ring features a 15-carat, "D-flawless" cushion cut diamond — literally the rarest and most expensive type of diamond on earth. The massive sparkler is also conflict-free, which was important to the couple. Kanye, who was deeply involved in the design process, wanted the diamond to look like it was floating on air. We think he achieved his goal. "She has the most perfect diamond and she’s a lucky girl, because she has a perfect eye and a perfect diamond," the ring's designer Lorraine Schwartz told InStyle about Kim's bauble. Congratulations again to Kim and Kanye! Now that you’ve seen the rock up close, tell us, what do you think?
