Vintage S.T. Dupont Ligne 1 Gold Plated Opal Mosaic Special Edition Lighter Working

This exceptional vintage S.T. Dupont Ligne 1 lighter is a genuine special-edition example, produced in limited numbers and distinguished by its elaborate iridescent mosaic treatment and richly textured gold-tone metalwork.

The broad front and back panels are covered with individually fitted opal-style mosaic fragments arranged in an intricate geometric composition. Each fragment reflects the light differently, producing vivid flashes of turquoise, cobalt blue, emerald green, violet, lavender, pink, orange and fiery red. The constantly shifting colors create remarkable visual depth and give the lighter an almost jewel-like quality when viewed from different angles.

The decoration continues across the lid and upper surfaces, allowing the mosaic design to remain prominent whether the lighter is displayed upright, held in the hand or viewed from above. Finely textured gold-tone borders frame the colorful panels, while the patterned side surfaces provide an elegant contrast to the luminous inlay. The combination of intricate mosaic work and warm metallic detailing gives the piece a dramatic and sophisticated appearance.

The underside is clearly marked “S.T. Dupont de Paris MADE IN FRANCE.” The proportions, construction and substantial feel are characteristic of the larger Ligne 1 format and reflect the precision craftsmanship for which S.T. Dupont became internationally recognized.

This lighter is in working condition. The ignition mechanism operates properly and produces a flame. The lid opens and closes correctly, and the striker and mechanical components function as intended.

The lighter measures approximately 2 1/4 inches tall and approximately 1 3/8 inches wide.

The gold-tone surfaces show scratches, marks and finish wear from previous use, consistent with the age and history of a vintage luxury lighter. The mosaic decoration continues to display exceptionally strong color, with brilliant iridescent flashes that become particularly striking under direct light.

What sets this piece apart is that it is not simply a standard Ligne 1 with decorative customization, but a true limited-production special edition. Only a restricted number were made, making surviving examples substantially less common than standard S.T. Dupont Ligne 1 finishes.

With its genuine special-edition status, limited production, elaborate opal mosaic decoration and unmistakable S.T. Dupont craftsmanship, this is a highly collectible and distinctive example for the serious S.T. Dupont collector. Its rarity, vivid color and uncommon decorative treatment give it strong appeal as both a luxury accessory and an important display piece.
