David Oscarson Harlequin Ruby Red GT Fountain pen

The Harlequin Collection is the sixteenth release in the prestigious David Oscarson™ series of Limited Edition writing instruments. Limited to just 88 pieces per color variation, this remarkable collection continues the legacy of fine craftsmanship and bold artistic expression that defines the brand.

As the follow-up to the sold-out Pierrot and Pierrette editions, Harlequin brings to life the iconic, mischievous character of Italian Commedia dell’arte. Known for his daring wit, playful defiance, and patchwork costume, Harlequin captures the spirit of resilience and creativity—a theme echoed in the intricate design and elaborate production of each pen in this series.

Masterful Craftsmanship: Guilloché and Hard Enamel

Crafted from 18-karat gold and .925 sterling silver, each Harlequin pen showcases the timeless technique of guilloché engraving, where precise, repetitive patterns are engraved into precious metal surfaces. The Art Deco-inspired diamond design is executed in multiple engraving stages, producing a dimensional interplay of lines, light, and texture.

To bring color and life to this structure, the engraved surfaces are meticulously filled with true hard enamel—a glass-like material created from finely ground glass, water, and metal oxides. This enamel is hand-applied in vibrant hues, then kiln-fired at over 1,000°F and polished to perfection. The result is a flawless, lustrous surface that enhances the depth of the guilloché beneath.

Diamonds and Design Details

Each Harlequin pen is adorned with three VVS-1 diamonds (0.016 carats each), precisely set in the crown, barrel end, and clip. These carefully placed accents add elegance and brilliance, enhancing the already sophisticated design.

Precision Engineering

The Harlequin Collection features a versatile filling system compatible with cartridge, converter, or eyedropper fill methods. A series of seals and O-rings ensures leak-proof performance. The pen is equipped with a Heidelberg-engineered 18kt gold nib, available in fine, medium, or broad sizes, and matched with an ebonite feeder for optimal ink flow and writing precision.

A rollerball version is also available for those who prefer an alternative to the fountain pen experience.
