Physical properties

Hardness of 6-7 on Mohs scale, colors ranging from pink to gray, dull to glassy luster, phaneritic crystal structure, specific gravity around 2.65-2.75.

Formation & geological history

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

Uses & applications

Widely used in commercial construction, countertops, monuments, and architectural facings due to its durability and aesthetic appeal.

Geological facts

Granite is the most common rock of Earth's continental crust and is exceptionally resistant to weathering.
