"Record-breaking ruby expected to sell for $30 million at auction"

A 55.22-carat ruby, named Estrela de Fura, is set to become the largest and most valuable ruby ever to appear at auction, with an expected sale price of over $30.3 million. The ruby was discovered by Canadian firm Fura Gems at one of its mines in Mozambique and possesses "outstanding clarity" and a dark red color known as "pigeon's blood." The stone will go on sale at Sotheby's New York in June and will be exhibited in various cities before the auction.
