Several points were noted:
– The crown, whose mount is flexible and lightweight, suffered deformation, initially probably due to the stress it experienced during its removal from the display case through the relatively narrow slot made by the angle grinder. This stress caused the crown's hoops to detach, one of which has already been lost in the gallery. Subsequently, a violent impact most likely crushed the crown.
– The crown originally featured eight palmettes of diamonds and emeralds, alternating with eight gold eagles. Today, only one of the eagles is missing. All the palmettes are present, although four have detached from the mount, some of them deformed.
– The diamond and emerald globe is intact and still attached to the crown's frame, with no missing elements.
-Originally composed of 56 emeralds, the crown still has them all, and of the 1,354 diamonds, only about ten very small ones, adorning the perimeter of the base, are missing, and nine are detached but have been preserved.
Although the crown's shape has been altered, almost all of its component parts are still present. Only one of its decorative elements is missing. Therefore, its complete restoration will be possible without resorting to reconstruction or re-creation. It will simply involve reshaping its framework.
