The S. T. Dupont Diamond Rain lighter uses their signature weather proof system. The case is made of 18 carat white gold which is rhodium plated to give it its unique shine. When the lighter is on its side the twelve carats (1,098 G quality diamonds) of diamonds appear to be falling like rain due to the special Diamond Rain pattern and Dupont’s signature diamond head pattern. Only three hundred and fifty two will be made and will be available exclusively through certain S. T. Dupont stores where their prestige collection is sold.
