Diamonds aren't just a girl's best friend - they're an important part of culture and commerce everywhere. Especially these gems here, which are widely regarded as the most expensive diamonds in the world. To uncover some details about some of the most beautiful objects in the world we've chronicled the ten most expensive diamonds ever.
10. A 56 carat heart-shaped diamond sold for $12 million at Christie’s in 2011. That price made this diamond the most expensive heart shaped one in the world. The gem has been praised for its symmetry and its craftsmanship.
9. The Chloe diamond has been valued at $16.9 million dollars. Guess Clothing founder Georges Marciano paid that amount for this type II stone (which means there are no nitrogen impurities within it) in 2007. Type II stones are exceedingly rare, the entrepreneur named the diamond after his daughter.
7. The Steinmetz Pink diamond is worth approximately $25 million dollars. With a weight of 11.92 grams or 59.6 carats, it is one of the world’s largest pink diamonds. At one time, this diamond was part of an exhibition at the Smithsonian Institute known as “The Splendor of Diamonds.”
