Granite is a natural stone formed from volcanic magma and is mainly composed of quartz, feldspar, and mica. It has a grainy appearance with visible patterns and variations in color. Granite is a hard and durable stone, but is susceptible to etching and staining if not properly sealed or maintained.

Quartzite is also a natural stone, but is formed from sandstone that has been subjected to high heat and pressure. It is primarily composed of quartz, with some other minerals present. Quartzite has a smooth and glassy appearance and is available in a variety of colors. It has a high resistance to heat, scratches, and stains, making it a popular choice for kitchen countertops.
