S.T. Dupont Ligne D Large Diamond Guilloché Ruby Fountain Pen
The S.T. Dupont Ligne D Large Diamond Guilloché Ruby Fountain Pen is a statement of luxury writing at the highest level — a piece where exceptional materials, masterful guilloché engraving, and precision French craftsmanship converge. As part of S.T. Dupont’s premier Ligne D collection, this edition stands out with its rich ruby-toned lacquer finish and iconic diamond guilloché pattern, establishing it as both a functional instrument and a collectible work of art.
The pen’s barrel and cap are finished in deep, lustrous ruby lacquer, applied over a precision-turned brass body. The surface is decorated with S.T. Dupont’s signature diamond guilloché — a repeating geometric engine-turned motif that catches light with subtle brilliance while offering tactile refinement. Polished gold-plated trim frames the body, with refined accents including the classic S.T. Dupont ring bands, clip, and cap top emblem, expressing elegance without ostentation.
The fountain version is equipped with a solid 14K gold nib, precisely engineered to deliver smooth, reliable ink flow with a responsive writing feel. Whether you choose a finer or broader nib grade, the 14K gold nib offers polished performance with line clarity and control — ideal for personal correspondence, journaling, or elegant desk work.
Designed for longevity and ease of use, the pen uses a cartridge/converter filling system (standard international style), giving you the flexibility to use convenient cartridges or your preferred bottled inks via converter. The balanced weight and refined proportion make the Ligne D Large comfortable for extended writing, while the rich ruby finish and guilloché detail make it a standout centerpiece in any collection.
Elegance, rarity, and precision engineering define the S.T. Dupont Ligne D Large Diamond Guilloché Ruby Fountain Pen — a choice for discerning writers and collectors who seek performance and presence in equal measure.
