Craftsmanship & Design

David Oscarson is celebrated for combining solid sterling silver with intricate guilloche and genuine vitreous enamel. Each Harlequin component begins with engine-turning to cut the diamond pattern directly into the silver. Multiple layers of powdered glass are then applied and kiln-fired, building a luminous field of color that preserves the crispness of the engraved geometry. The final hand polishing reveals remarkable depth, allowing the pattern to appear and disappear beneath the enamel depending on the angle of view.

Because the structure is cut into sterling silver rather than stamped or printed, the line quality is clean and enduring. The weight is substantial without feeling cumbersome, and the cool touch of silver contrasts beautifully with the warmth of the enamel, underscoring the collection's elegant tension between precision and play.

Writing Experience

An 18k gold nib provides a smooth, confident line with a touch of natural spring. Offered in fine, medium, and broad, it suits everything from precise annotation to expressive journaling. Ink delivery is managed through an international cartridge or converter, making the Harlequin practical for both travel and dedicated desk use. The sterling construction contributes a reassuring balance, encouraging an unhurried, controlled hand that rewards longer writing sessions.

Brand Heritage

Since its founding in 2000, David Oscarson has pursued a singular vision: to bring engine-turned guilloche and hot enamel back to the forefront of fine writing instruments. Produced in small batches, each collection focuses on a distinct pattern language and enamel palette, executed with techniques more often associated with high horology and decorative arts. The Harlequin series exemplifies this approach, uniting classical craft with contemporary color to create pens that resonate with enthusiasts and serious collectors alike.
