Bossert & Erhard Diamond Limited Edition Fountain pen

The Bossert & Erhard Diamond Limited Edition Fountain Pen is a remarkable showcase of German precision engineering and luxury craftsmanship. Limited to just 99 pieces worldwide, this exclusive fountain pen is handcrafted from solid 925 sterling silver and distinguished by an extraordinary surface consisting of 3,200 precisely milled pentagons across the cap and barrel. Inspired by the brilliance and geometry of a cut diamond, the Diamond transforms technical perfection into a sculptural writing instrument of exceptional beauty.

Every facet has been meticulously machined to create a dynamic surface that captures and reflects light from every angle. The striking silver body is complemented by partially gold-plated sterling silver fittings, including the clip, cap top, cap ring, and cone, creating a refined contrast that enhances the pen's luxurious appearance. Entirely handcrafted and assembled in Germany, the Diamond is a collector's piece that perfectly balances artistry, innovation, and timeless elegance.

A Masterpiece of Precision

The Diamond is one of the most technically impressive models in the Bossert & Erhard Universe Collection. The intricate pattern of 3,200 individual pentagons requires exceptional machining precision and expert finishing, resulting in a multidimensional texture unlike any other luxury writing instrument. Combined with a mirror-polished finish and a solid spring-loaded clip, every detail reflects the brand's century-long dedication to excellence.

For an even more personal touch, the sterling silver clip can be engraved, making the Diamond an extraordinary heirloom or commemorative gift.

Hand-Engraved 18-Carat Gold Nib

At the heart of the Diamond lies a magnificent 18-carat (750) solid gold nib with a durable iridium tipping point, delivering a smooth, expressive, and highly refined writing experience. Every nib is individually hand engraved by a master engraver, with four elegant engraving patterns available to create a truly personal writing instrument. This meticulous craftsmanship transforms each nib into a miniature work of art while ensuring outstanding writing performance.
