Quartz is a natural material, in fact, it's one of the hardest minerals on Earth. This makes quartz a great material to be used in countertops. However these countertops are not quarried like granite and marble, Cambria countertops are what we call "engineered countertops." This means that the quartz is combined with binders and pigments to create incredible surfaces. As the manufacturing process allows the addition of pigments, a wide range of colors and styles are available, including ones that look like natural stone countertops such as granite and marble!
