Swiss DiamondLocated in the heart of the Swiss Alps, Swiss Diamond® produces some of the world's highest-quality cookware including frying pans, pots, roasters, woks and more. Swiss Diamond is manufactured by Swiss Gourmet Group AG in the city of Sierre. One of the world's leading cookware brands, Swiss Diamond creates durable nonstick cookware, which features a patented, diamond-reinforced surface with real diamond crystals embedded in the surface. A gold medal winner at the Inventor's Fair in Geneva, Swiss Diamond's revolutionary cooking surface is easy to wash, and resists peeling, cracking, or blistering. Swiss Diamond's patented diamond-reinforced surface is safe to use with metal utensils, and is even dishwasher safe, though Swiss Diamond recommends hand washing. The surface contains no PFOA, and retains its nonstick abilities for the life of the cookware. Durable and long-lasting, Swiss Diamond cookware is built to last a lifetime. In addition to providing high-quality cookware, Swiss Diamond prides itself on its eco-friendly processes. Swiss Diamond embraces energy efficiency by using electricity generated mostly from hydro-electric power plants.
