By on March 20, 2013

Large diamonds, with a big carat weight, and also a perfect cut, flawless clarity and brilliant colour, are extremely hard to come by. So when they go to auction, the top auction houses in the world are desperate to sell them, and the world’s most famous collectors, willing to pay high prices. Here is a run down of the 5 most valuable diamonds sold at auction.

5. The Chloe White Diamond


This diamond was purchased for $16.2m at Sotherby’s in Geneva in 1997 by the founder of Guess, Georges Marciano. He named the stone after his daughter. It’s an impressive 84.37 carat, has the highest grading possible for a diamond and is brilliant cut – the most difficult cut to achieve from a rough diamond.

4. Star of the Season White Diamond


This incredible 100.1 carat weight diamond was sold for a then-record $16.5m by Sotherby’s in 1995. The internally flawless diamond was bought by Sheik Fitaihi of Saudi Arabia, who has amassed a large and expensive collection of diamonds and jewelry.

The stone – an incredible 24.78 carat weight – was snapped up by Laurence Graff. The London jeweller immediately renamed it the Graff Pink. It’s classified as a “fancy intense pink” which is the best rating for a pink diamond. The stone is mounted as a silver diamond ring with two flanking diamonds.
