The Silestone Platinum Series is the newest and most advanced innovation in the quartz surfacing market. The Platinum Series offers four unique colors with distinctive metallic-like accents that integrate the performance of Silestone´s bacteriostatic properties and the chic look of stainless steel. The Platinum Series colors include Chrome, Zirconium, Carbono and Steel. This series is ideal for consumers and designers looking to incorporate the latest design trends with the functionality of a surface that is scratch, stain and scorch resistant.


Volcano Series

The Volcano Series introduces an entirely new tactile and aesthetic experience for kitchen and bath design projects while offering all the benefits of Silestone natural Quartz.

The unique texture of the new Volcano Series creates a contemporary matte look and feel. Using a new technology to apply a lightly indented effect to the quartz surface, Volcano makes a stylish design statement. At launch, the collection will be available in five colors. Nuit Bleu, a new cool smoky charcoal color with hints of natural stone, will launch with the collection. The other colors are four Silestone bestsellers: Haiku, a light cream; White Zeus, pure white; Kensho, a soft ash grey; and Grey Expo, a natural grey hue.

Influenced by European design trends, the subtle molten-rock texture of the surface creates depth and inspires new possibilities for stunning residential and commercial applications. Incredibly versatile, Volcano can be used for kitchen countertops, vanity tops, wall paneling, custom-made furniture, and more.
