How much are the British Crown Jewels worth?

The Crown Jewels have been valued by some people at 20 million pounds (39 million dollars). I must point out that this is pure speculation, as the Crown Jewels have not been valued, only for insurance purposes, and this is kept secret.

No they're actually worth inexcess of £20 Billion, and that's a very conservative estimate, some say they are actually priceless.

The Diamond in the royal scepter...The Star of Africa alone is estimated to be worth $400 million. 20 billion pounds is a bit much....The total worth of the crown jewels is probably closer to 3-5 Billion.
Of no real value in a way! Although priceless, if they were stolen they could never come on the open market to be sold as everyone would know what they are. So no price could be put on them They could, however, be altered - e.g. the gold could be melted down and the precious stones could be cut up and repolished into smaller ones. In this case the value would decrease considerably as large diamonds are so much more rare than smaller ones and hence far more valuable. So, the short answer is no one knows. Incidently, the Crown jewels, for this reason, are not even insured. After all, who in their right mind would want to pay out if they were stolen? However, the security surrounding the jewels, despite the fact that they are freely on view in he Tower of London, is state-of-the-art.
