Granite Crystal Stones

Byname

Granite is a light-colored volcanic rock. It is the most common plutonic rock in the Earth's crust, formed by deep magma (silicate melting) cooling. Granite mainly produces small amounts of mica, amphiboles, and other minerals using quartz and feldspar. This mineral structure usually gives granite a red, pink, gray, or white color. Large mineral crystals in granite are evidence of slow cooling from molten rock.

Granite is tough to withstand abrasion, strong enough to withstand considerable weight, has enough inertness to withstand the weather, and it adopts an excellent polish. These features make it a very useful stone. Granitic rocks are given special names based on their crystal size. If a granite rock has a particularly large crystal (more than a centimeter), it is called a "pegmatite". If the shallow is a particularly good crystal rock, it can be called "aplite".
