Quartz (engineered stone) is a man made product that is the fastest growing type of countertop surface on the market today. While it does have some real advantages, many people still prefer the real stuff (Granite / Marble). But, engineered stone is giving the natural stone some serious competition. Engineered stone is marketed by it’s manufactures as the best countertop for busy kitchens. It is both stain and heat resistant and does not need to be sealed. It is available in natural stone type colors and grains, as well as vibrant colors not found in nature. Consumer reports, in August 2007, ranked it best for durability and low maintenance. The number one disadvantage seems to be that seams are more visible than with natural stone.
