Guilloche is an intricate decorative technique created by engraving a surface with great precision and then adding a transparent layer of resin, enamel, or in the case of S.T. Dupont’s fine writing instruments, a natural lacquer over the engraved surface. The solid brass body and cap is lacquered multiple times and hand polished to create a smooth, unique texture on the surface that differs from each pen as no two writing instruments are identical.

The 'Diamond Guilloche' collection features the namesake technique that is French for "engine turning." The diamond design is created by an engine turning process that engraves very precise, intricate, geometric patterns into an underlying material. For this latest launch, S.T. Dupont selected a finely detailed diamond pattern which is then overlaid with sumptuously colored Urushi lacquer, the result is simply spectacular.

S.T. Dupont's artisans add layers of natural lacquer to the surface of the diamond patterned guilloche in a months long process involving many applications and polishing to impart depth and mystery to each finish. The engraving causes the reflection of light through the overlay of natural Urushi lacquer creating a stunning display of light and color.
