DiamondFinish 

Hard-wearing finish 
DiamondFinish keeps your cooktop looking like new for longer, as the special ceramic glass coating significantly reduces scratches. DiamondFinish is more than twice as hard-wearing as conventional ceramic glass surfaces. Thanks to our scratch-resistant surfaces, there are 80 % fewer scratches due to sand. At the same time, the high-end gloss gives your cooktop an elegant appeal.
