Granite

Granite is the most common igneous rock in the earth's crust and one of the hardest. It was formed ages ago when magma (molten rock) cooled. This cooling took place below the earth's surface and slowly enough to permit formation of crystals. Granite has been formed in all the periods of geological time. If a piece of granite is crushed to powder, one can easily pick out tiny fragments of the separate substances or minerals, that compose it, which are: quartz, feldspar and mica. The color of granite depends on the proportion and varieties of the minerals in it.

Granite is one of the hardest materials on earth. The beauty and elegance of granite makes it the most prestigious and practical countertop. No two slabs of granite are the same, they are all different, and so your work surface will be unique.
