Granite is a natural, igneous rock composed of quartz, feldspar, micas, and a mixture of additional trace minerals. Forbes explains they types and amounts of the different minerals are what give granite different colors, textures and patterns. It typically 10 to 50% quartz, which is semi‐transparent white, and 65 to 90% feldspar, usually pinkish or white. Generally, natural stone like granite is desirable because it has more character than man‐made countertop surfaces.
Depending on the size of your countertop and how many separate areas you have, you may need more than one slab. It‘s best not to rely on samples when it comes to making your granite choice. You can do some preliminary sampling to get an idea of what you might like and what will match your color scheme best, but make sure to choose the exact slab yourself.
