Diamond crystals form an indestructible non-stick cooking surface on Swiss Diamond cookware. And you can count on quick, efficient and even heat conduction. Our fry pan is made of thick 6mm pressure cast aluminum and has a perfectly flat base that will not warp. The pan can be used on ceramic, gas, and electric cooking surfaces. Made in Switzerland, Swiss Diamond non-stick cookware is covered by a limited lifetime warranty. Molly has selected a 10" fry pan.
