The Bohème Je t'aime existed in several versions: of black precious resin (resin), of sterling silver as well as of white gold, in each case as cartridge fountain pen and ballpoint. The precious-resin variant is a real version made by Montblanc but no longer appears on the Montblanc website today, since the series was discontinued. The white-gold version was around 11,000 euros per piece and had hearts of real rubies on the clip. Current prices for the other variants can most reliably be enquired about directly with Montblanc or in a boutique.
