The Modernist Exclusive Diamond is a pen made by hand from 230 thousand pounds, created by Caran d’Ache in homage to architect Antoni Gaudí.  This creation, covered in rhodium, has a pen in 18k gold, blithely finished.

The trunk is covered with 5072 diamonds for a total of 20 carats. On the roof are willing Jewel 96 rubies cut in half (0.32 carats), who write the monogram “SO”. The amazing value made easy entry into the Guinness World Records.
