Non-stick diamond coating applied by nanotechnology, no PFOA. Swiss Made quality 100% manufactured in Switzerland. Very high thermal conductivity thanks to the fusion of thick aluminum and the diamond coating. High-pressure aluminum die-casting, non-deformable thermal base with plasma anti-corrosion treatment of the internal surface. Resistant handles, knobs and glass in the oven up to 260° C. Lids (if any) in tempered glass, shock-resistant edge in steel and adjustable valve for steam vent.

A bit of history ... to understand better.
Swiss Diamond, a brand of excellence in the production of high quality cookware. The company was founded in 1974 and maintains its headquarters and production in Sierre, in the heart of the Swiss Alps.
The ever increasing demand for non-stick cookware led the company to develop a revolutionary coating reinforced with real diamond crystals in 2000. This innovative and patented technology is recognized and awarded with the gold medal at the Inventor Fair in Geneva.
In 2010, after four years of extensive research and testing, Swiss Diamond's engineers have improved and further enhanced the coating to which they give a lifetime warranty for non-stick.
Swiss Diamond products are currently sold in at least 38 countries worldwide.
