What is Granite? 

Familiar as a mottled pink, white, grey and black ornamental stone, Granite is the most common intrusive rock in the Earth’s continental crust. Granite’s three main minerals are feldspar, quartz, and muscovite, or biotite mica. Of the three typical minerals, feldspar predominates, and quartz usually accounts for more than 10 percent. Wherever it has been available, its strength and durability have made it a first choice for everything from temples to milestones.
