Block of raw black granite being cut into slabs by large diamond tipped saw
Granite is - quite literally - as old as the earth. It is formed from liquid magma, the molten rock still found at the core of the planet, cooled slowly to form a substance approaching the hardness and durability of diamond. Granite is an igneous rock the name reflecting its fiery beginnings. However, granite owes it hardness and density to the fact that it has been solidified deep within the earth, under extreme pressure. Over the eons, seismic activity has changed the crust of the planet, forcing veins of granite to the surface. Glaciers scraped off layers of dirt, sand and rock to expose granite formations. Typically revealed by outcrops, these deposits have been discovered on all of the continents.
