The body parts of the Solitaire Mozart were and are made in the former Cartier factory in France, which was taken over by Montblanc years ago. For this reason, according to EU legal requirements, the country of origin 'France' is to be applied to the writing instrument.

'Ag925' stands for sterling silver 925 and is in content identical with the pure number 925. The fountain pen is thus a regular original.
