Insane: This Diamond Ring Sold for the Most Ever at Auction

We've heard of plenty of überexpensive rings in our time, but the latest big-number bauble has truly blown our minds. The Cartier 25.59-carat Sunrise Ruby ring, shown above, was sold at a Sotheby's auction yesterday for an astounding $30 million. 

The piece was anticipated to fetch anywhere from $12 to $18 million but far exceeded those comparatively wimpy expectations. As a point of comparison, allow us to remind you that Elizabeth Taylor's 33-carat diamond engagement ring from Richard Burton is worth only $8.8 million.
