Soapstone is another natural stone that makes for great kitchen countertops. It does not have a wide variety of colors like granite, but it is definitely a unique and beautiful stone. It mostly comes in shades of gray and black, and occasionally beautiful white veining. Over the years, soapstone countertops will darken and develop a beautiful patina. This process can be aided by periodically applying mineral oil to darken the stone and bring out the natural veining. Soapstone is a very unique and rustic stone that can add beauty to any kitchen.
