Cosentino. Silestone quartz countertops are available in two new color series. The Galactic series (pictured), a line of earthy hues with a unique speckle-pattern finish, is inspired by the natural movement of stones and galactic rocks, with colors including black, brown, gray, and cream. The Nebula collection is composed of six colors that create movement through veining and add depth to any kitchen or bathroom, according to the manufacturer. As with all Silestone quartz countertops, both series are non-porous and do not need to be sealed, the manufacturer says. They are easy to clean and have high scratch-, stain-, and heat-resistance, the company adds. 866.268.6837. www.silestoneusa.com.
