1. Mariah Carey
A lot of people may call Nick Cannon corny, but there’s nothing corny about the engagement ring the new father of twins bought for his butterfly of a bride. Mariah Carey rocks a one of a kind $2.5 million, 17 carat, emerald-cut diamond by Jacob and Co. It flaunts a center pink stone of 10 carats with 58 smaller pink diamonds surrounding it while two half-moon cut diamonds hug its sides.
