The world’s priciest diamond? Up to $55M – CNBC

Time to start searching for that perfect Christmas gift? It’s your lucky day, big spender—one of the world’s most expensive diamonds goes up for auction in November.


A rare 12-carat, blue-colored diamond, known as Blue Moon, is expected to fetch $35 million to $55 million in a Nov. 11 Geneva auction, international auction house Sotheby’s said Thursday.


If it does fetch that price, it would be the most expensive blue diamond ever sold, beating the Zoe Diamond, which sold for $32.6 million in 2014, Sotheby’s said. To set the world record price for any diamond put to auction, Blue Moon must sell for more than $46.2 million.
