Physical properties
Hardness: 6-7 on the Mohs scale; Color: Pink, reddish, with white and black speckles; Luster: Vitreous to dull; Crystal Structure: Phaneritic (coarse-grained, visible interlocking crystals); Cleavage: Good in feldspars; Specific Gravity: 2.65 - 2.75
Formation & geological history
Formed by the slow cooling and crystallization of magma rich in silica and alkali elements deep beneath the Earth's crust over millions of years.
Uses & applications
Widely used in construction for dimension stone, countertops, floor tiles, monuments, curbing, and facing stone.
Geological facts
Pink granite gets its distinctive rosy hue from an abundance of potassium feldspar (orthoclase). It is one of the most common continental crust rocks on Earth.
Field identification & locations
Easily identified by its interlocking, coarse-grained crystals of pink feldspar, clear to smoky quartz, and dark mica flecks. Found worldwide in major mountain ranges and cratons.
