How A Flawless $300,000 Diamond Was Lost In An Formula 1 Car Crash

For the 2004 Monaco Grand Prix, Jaguar's cars were fitted with newly designed nose cones to promote the film Ocean's Twelve. Diamonds worth in excess of $300,000 were attached to the nose of each car. If you think that's crazy, wait for more.
It happened on the first lap. Jaguar driver Christian Klien crashed his diamond-encrusted F1 car at the Loews Corner. Track safety regulations prohibited Team Jaguar from searching for the diamond until after the race ended two hours later. Of course, by the time the Jaguar folks arrived on the scene, the diamond was long gone. No one knows what happened to it.
