The idea of stealing something so prominent and so unique would be rather good for an "Entrapment" or "Mission Impossible" style of a movie. Why is it here, so outside the usual profile of the team and its typical objective of a con on a shadowy character? Because in fact the theft as such is not the objective, and this becomes obvious only at the very end of the plot.
A few elements in the plot appear almost naive, such as cracking of the security measures. As if that would be so easy... Aside of this, the convoluted storyline buries deeply the real objective of the con, and the purpose of the seemingly unrelated events and series of preparatory distractions. The most funny on the plot is that Her Majesty Police is in fact providing the "proof of authenticity" for the chunks of glass which will be "sold" several times to several shadowy collectors. I have not seen that coming!
