What is Silestone’s Reliability?

Silestone Quartz has unparalleled durability and strength. It is made of Natural Quartz, which is the 4th hardest mineral found in nature. The only natural minerals harder than quartz are diamond, sapphire and topaz. Silestone countertops are made of a hard, dense and non-porous material that is consistent throughout its composition, making it more reliable than any other natural stone.

What is Silestone’s Antimicrobial Protection?

Silestone is National Sanitation Foundation (NSF) approved and GREENGUARD-certified to be safe for the kitchen indoor environment, which makes it a cleaner and safer than other surfaces. Silestone countertops are the only surfaces made with built-in antimicrobial protection that safely fights the growth of microbes such as odor causing bacteria, mold, and mildew for the life of the product. This makes Silestone countertops and surfaces easier to clean, and they stay cleaner between cleanings.

What is Silestone’s Scratch Resistance?

Common household accidents such as a dropped knife, a fallen piece of glass or errant scissors will not scratch Silestone because only materials as hard as, or harder than Silestone will scratch it. Beware: no surface is indestructible.

We recommend the use of trivets when placing hot items on a Silestone surface to avoid thermal shock.
