One of the best countertops is premium quartz. It is classified as artificial stone because it is composed of approximately 90% ground quartz and 8-10% resins, polymers, and pigments. Quartz has the longest lifespan of any countertop material, and you don’t have to worry about it breaking easily because it is stain and heat/scratch resistant. Your first choice for a kitchen countertop should always be premium quartz.
