New in Box. The Harlequin Collection is the sixteenth in the David Oscarson series of Limited Edition writing instruments. Produced in five color variations, each will be limited to production of 88 pieces (including fountain pens and roller balls). This is a rollerball pen. In the spirit of artistic mastery and the tradition of Old World craftsmanship, this inspiring Collection combines the centuries-old technique of Guilloch with the art and expertise of Hard Enamel. The Harlequin Collection incorporates multiple levels of Guilloch engraving and five colors of translucent (Red, White, Yellow Green and Blue) and Opaque (Black) hard enamel. Hand-crafted from 18-karat gold and .925 Sterling Silver, each precious metal component passes through multiple stages of precision engraving, creating an intricate pattern known as guilloch; a painstaking process which brings life and light to the surface of precious metals. The Art Deco design of this Limited Edition requires multiple stages of engraving. The entire body of the pen is first cut down to the level of the sunburst background, leaving the outlines and centers of the interlocking diamonds in high relief. The sunburst patterns are then engraved onto the surface of the body of the pen, maintaining the integrity of the outlines and diamond centers in high relief. Using a mortar and pestle, a composition of glass, water and metal oxides is ground for hours by hand. When settled, the water is removed, leaving the fine paste that is the basis for hard enamel. A quill is then used to apply each coat of the mixture to the surface of the metal, ensuring that the entire guilloch area is completely covered in enamel. The components are then fired in a furnace at temperatures exceeding 1,000 F, fusing the enamel to the metal and forming a layer of glass. After cooling, the pieces are manually ground with a diamond file, restoring their proper shape and surface. This tedious process is repeated at length until the level of enamel reaches the depth required to cover the peaks and fill the valleys of each intricate guilloch pattern. When the final stages of firing are completed, the pieces are polished and buffed, revealing the velvet finish of translucent hard enamel. Production of translucent hard enamel demands the highest levels of patience, experience and skill. A five-year apprenticeship is required to ensure that the highest levels of quality will be met in each individual Collection piece. Diamonds Each Harlequin piece is set with three VVS-1 diamonds (.016 carats each): one in the top of the crown, one in the bottom of the barrel and one in the clip. Limited Edition # 11/88.
