Physical properties
Hardness: 6-7 Mohs; Color: Pink, white, and grey; Luster: Vitreous to dull; Structure: Coarse-grained (phaneritic); Cleavage: Perfect in two directions for feldspar components.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface. It is a plutonic rock that cools over millions of years, often dating back to the Precambrian or Paleozoic eras.
Uses & applications
Used extensively in construction for countertops, floor tiles, paving stones, curbing, monument carvings, and as a decorative architectural stone.
Geological facts
Pink granite gets its distinct color from an abundance of potassium feldspar (orthoclase). It is the most common crustal rock on Earth’s continents.
Field identification & locations
Identify in the field by its interlocking 'salt and pepper' crystalline texture and the presence of pink feldspar, clear quartz, and dark biotite or hornblende. Commonly found in mountain ranges and continental shields.
