Confirmation finally happened when a three-dimensional leaden model of the latter was rediscovered in the archives of the National Museum of Natural History in Paris in 2005. Previously, the dimensions of the French Blue had been known only from two drawings made in 1749 and 1789; although the model slightly differs from the drawings in some details, these details are identical to features of the Hope Diamond, allowing CAD technology to digitally reconstruct the French Blue around the recut stone. The leaden model revealed 20 unknown facets on the back of the French Blue. It also confirmed the diamond underwent a rather rough recut that removed the three points and reduced the thickness by a few millimeters. The Sun King's blue diamond became unrecognizable and the baroque style of the original cut was definitely lost. Historians suggested that one burglar, Cadet Guillot, took several jewels, including the French Blue and the "Côte-de-Bretagne" spinel, to Le Havre and then to London, where the French Blue was cut in two pieces. Morel adds that in 1796, Guillot attempted to resell the "Côte-de-Bretagne" in France but was forced to relinquish it to fellow thief Lancry de la Loyelle, who put Guillot into debtors' prison.
