    Which Types Of Granite Make The Best Countertops?

    Granite is an intrusive igneous rock, which means that it’s formed by magma slowly cooling below the surface of the earth. True granite is a mixture of several different minerals, including quartz, mica, silica, feldspar, and other trace minerals that lend different colors to the stone. As the magma cools, the amount or concentration of each mineral may vary from section to section causing variations.
