The concept behind the TWSBI Diamond 530, 540, and 580 was to return to the roots of writing culture and capture the simplicity and elegance of traditional writing instruments. In recent years, with the modernization of writing tools, classic fountain pens had begun to fade into obscurity. With the Diamond series, our aim was to revive this heritage by offering a fountain pen that feels timeless yet is fully appreciated in today’s world.

By combining the traditional mechanics of a fountain pen with a modern industrial design, it becomes an eye-catching instrument that honors the past while fitting seamlessly into the present. Its piston-filling system sets a benchmark in reliability, and all components are detachable. This allows you to disassemble and reassemble the pen yourself – an experience that reflects the authenticity of traditional fountain pen ownership.
