Granite is a naturally occurring stone that is quarried from the ground and sliced into thin slabs before being polished and built into counters. It's an igneous rock formed via slow magma crystallization deep under the Earth's surface.
The stone is light-hued and features big, visible grains. The material is mostly made of quartz and feldspar, with minerals responsible for its color, which ranges from red to pink to grey or white.Quartz CompositionQuartz countertops
are called engineered stone countertops, which can contain a lot of natural quartz as well as various minerals. A quartz countertop isn't slabs of quarried stone but rather results from crushed stone byproducts that are molded into slabs for countertops and other goods.
Engineered quartz, which is a manufactured stone composed of 97 percent crushed quartz crystals and 3 percent resins, is produced from natural quartz. Quartz comes in a variety of colors, designs, and textures.
