Hollow Rock Designs. Made of gray-green cement with a thin charcoal vein, this countertop complements stainless steel and cream-colored cabinets. Instead of polishing the concrete to a gloss, the fabricator polished it to be soft to the touch. The cabinet lends soft tones to the kitchen, the maker says, and was used in a Craftsman-style home. 218-834-7800. www.hollowrockdesigns.com.
