Silestone Steel is a Quartz stone with grey background along with metal inserts all over it which gives distinct look to the surface. Silestone is a material made by joining characteristics of quartz and versatile crude materials. This mix makes an unimaginably durable material that is ideal for countertops in the kitchen and restroom. In mix with the raw materials added, Silestone becomes scratch safe and profoundly impervious to gouges and stains. There is no danger of lasting staining from basic kitchen fluids like espresso, wine and oil.
