Physical properties
Hardness: 6-7 on Mohs scale; Color: Pinkish-red, white, gray, and clear; Luster: Dull to vitreous; Texture: Phaneritic (coarse-grained) showing distinct crystals of potassium feldspar (pink), quartz (translucent gray), and mica (shiny flakes).
Formation & geological history
Formed by the slow cooling and crystallization of silica-rich molten magma deep within Earth's continental crust over millions of years.
Uses & applications
Widely used as a dimension stone, decorative landscaping rock, building material, countertops, and paving stone due to its durability and aesthetic appeal.
Geological facts
The distinct pink color in pink granite comes from potassium-rich orthoclase feldspar. Granite makes up a large portion of Earth's continental crust.
Field identification & locations
Identified by its visible interlocking crystal grains composed of pink feldspar, clear-gray quartz, and dark or shiny mica. Extremely common worldwide in continental shield areas.
