Whatever happened to the diamond that went missing in F1 crash?

A $300,000 diamond was last seen stuck to the front of an F1 car before it crashed on the first lap of the Grand Prix and it still has not been found 22 years later. The reason why a 1.4 carat diamond was attached to the most delicate part of a car that reaches 200mph in a race was straightforward: publicity.

Jaguar Racing's results on the track had been mediocre at best since becoming an F1 team in 2000 and by 2004 its parent company Ford had decided it would be pulling them out of the sport. "My job flipped from primarily running the team to primarily selling the team and finding a new owner or they would shut it down," former team principal Tony Purnell tells BBC Sport.

They had enjoyed a successful promotional weekend in Silverstone the previous season thanks to a tie-up with Terminator 3 and so director of communications Nav Sidhu was looking to recreate the magic with another bit of help from a movie.
