Red diamonds are the rarest of the rare. In fact, there are believed to be less than 30 red diamonds in the world today, and most are less than half a carat in weight. With good reason, a single carat of true red diamond sells for well over $1million. This diamond might go for ten times that.
An extremely rare 2.11-carat Fancy Red diamond is up for sale. It was discovered at Rio Tinto, an Argyle diamond mine in Western Australia.
