Extremely rare and highly sought-after, this S.T. Dupont Ligne 1 features an exceptional opal mosaic inlay, a decoration seldom seen on the market. Pieces with gemstone or opal inlays are prized by collectors and often attract intense bidding when they appear at auction due to their unique craftsmanship and limited availability. Authenticity The base is engraved with “S.T. Dupont de Paris – Made in France” along with the serial number “V6CN21.” The opal inlay work is consistent with artisan-applied custom or special-order decoration associated with vintage Dupont workshops and independent specialist artisans of the era. [Appearance] Shows age-related wear on the gold-plated surfaces including scratches, discoloration, scuffs, and plating loss, especially along the edges and base plate. The opal mosaic panels exhibit vibrant color play with blue, green, and red flashes; some gaps, minor chips, and irregularities can be seen due to the nature of hand-laid stone inlay and long-term aging. Please refer closely to the photos for full condition details. [Functionality] Basic ignition has been tested and confirmed. As this is a vintage lighter, a professional overhaul is recommended for long-term use. Functions beyond basic ignition are untested and not covered by warranty. [Accessories] Everything shown in the photos is included.
