Pink Granite

Physical Properties

Hardness: 6-7 Mohs; Color: Pink, reddish-orange with grey and white specks; Luster: Dull to vitreous; Crystal structure: Phaneritic (medium-to-coarse grained); Cleavage: None (though feldspars within it have cleavage); Specific gravity: 2.63 to 2.75

Formation & Geological History

Formed by the slow crystallization of magma below the Earth's surface (intrusive). The pink color comes from a high concentration of potassium feldspar (orthoclase). Found in continental crust worldwide, dating from the Archean to the Cenozoic eras.

Uses & Applications

Used extensively in construction for countertops, floor tiles, paving stones, and monuments. High-quality specimens are popular for rock tumbling and decorative lapidary work.

Geological Facts

Granite makes up a large portion of the Earth's continental crust. El Capitan in Yosemite National Park is one of the most famous granite monoliths in the world.

Field Identification & Locations

Identify by its interlocking crystalline texture and visible grains of pink feldspar, translucent quartz, and dark mica or hornblende. Commonly found in riverbeds or mountain outcrops in crystalline shield regions.
