Fountain pen from Montblanc's special-edition Meisterstück Solitaire series "Czar Nikolai I" Barrel and cap in sterling silver vermeil (925 silver with gold plating), with "925" hallmark visible on the barrel. Cap set with a natural malachite finial, showing the characteristic natural banding of the stone.

Tested with ink and confirmed in full working order (writing sample photo included). Large/LeGrand size. Visible light wear to the gold plating in high-contact areas (barrel ridges, cap rim), with spotting from oxidation of the underlying silver, consistent with genuine use over 25+ years.
