Dolomite is a natural stone that forms on the earth's surface. Quartz is an engineered stone. It's about 90% quartz material bound in a mixture of pigments and resin. Quartz countertops are non-porous, meaning they won't stain, and you don't have to seal them. On the other hand, dolomite is a porous stone you'll need to seal annually.Web
