What does the most expensive ring in the world look like? Now we know. The Cartier "Sunrise Ruby" ring (above) fetched a record-breaking $30 million at a Sotheby's auction in Geneva earlier this week (and greatly exceeded estimates that ranged from $12 million to $18 million).

The wow-worthy piece features an exceptional and immeasurably rare cushion-cut 25.59-carat Burmese ruby set between between shield-shaped diamonds weighing 2.47 and 2.70 carats—and it set a world record as the highest-selling ruby at auction as well as for any jewel by Cartier. This is definitely one piece of bling we wouldn't mind receiving as a gift.
