Physical properties
Mohs hardness of 6-7, distinct pink to reddish coloration due to potassium feldspar, glassy quartz veins, vitreous luster, granular to massive crystal structure, specific gravity around 2.65.
Formation & geological history
Formed by the slow cooling of magma rich in silica and alkali metals deep beneath the Earth's crust, typically over millions of years during various geological eras.
Uses & applications
Commonly used in construction, monument building, countertops, architectural facing, and as decorative landscape gravel or tumbling rough for lapidary work.
Geological facts
Pink granite gets its vibrant color from potassium feldspar (orthoclase). Granite is a primary component of the continental crust.
Field identification & locations
Easily identified by its interlocking crystalline grains of pink feldspar, translucent quartz, and dark biotite mica. Found worldwide in shield areas and mountain roots.
