6 ct. Fancy Blue Diamond

A flawless blue diamond represented by Sotheby's Hong Kong sold at auction for $7.98 Million U.S. Dollars to Moussaieff Jewellers of London. The 6.04 carat, internally flawless blue diamond fetched a record breaking $1.32 Million U.S. Dollars per carat making it the most expensive diamond per carat in history. The previous record price paid for a fancy colored diamond was the $926,000 per carat which was paid for the "Hancock Red" in 1987. Moussaieff Jewellers has a reputation for aquiring extremely rare and costly gemstones.

Blue diamonds have long captivated the rich and powerful -- shimmering with a certain dark mystique. The famous "Hope Diamond", a 45.52 carat grey-blue beauty, was passed down through the ages by King Louis XIV of France, Marie Antoinette and American heiress Evalyn Walsh McClean among others. It now rests in the Smithsonian Institute in Washington D.C. The selling price for blue diamonds is often ten times the price for white (colorless) diamonds of similar quality.
