Physical properties

Hardness of 6-7 on Mohs scale, commonly pink, gray, or white with visible mineral crystals, vitreous to dull luster, specific gravity of 2.65-2.75.

Formation & geological history

Formed from the slow cooling of magma rich in silica and alkali feldspar deep beneath the Earth's surface over millions of years.

Uses & applications

Widely used in construction for countertops, flooring, monuments, and curbing due to its high durability and resistance to weathering.

Geological facts

Granite is the most common intrusive rock on Earth and forms the foundation of many continental mountain ranges.
