Pink Granite
Granite (composed primarily of potassium feldspar, quartz, plagioclase feldspar, and biotite/amphibole)
Hardness 6-7 on the Mohs scale, phaneritic (coarse-grained) texture, vitreous to dull luster, specked pink, white, grey, and black color, no cleavage as a whole rock but feldspar minerals within display distinct cleavage.

Physical properties
Hardness 6-7 on the Mohs scale, phaneritic (coarse-grained) texture, vitreous to dull luster, specked pink, white, grey, and black color, no cleavage as a whole rock but feldspar minerals within display distinct cleavage.
Formation & geological history
Formed by the slow crystallization of silica-rich felsic magma deep beneath the Earth's surface (plutonic environment) over millions of years, allowing large, visible mineral grains to develop.
Uses & applications
Widely used as dimension stone in architecture, building cladding, paving, monuments, countertops, and structural masonry due to its strength, durability, and aesthetic appeal.
Geological facts
Granite makes up a large portion of the Earth's continental crust. The pink or reddish coloration in this specimen is caused by abundant orthoclase or potassium feldspar.
Field identification & locations
Identified in the field by its coarse interlocking crystals of visible pink feldspar, clear-grey translucent quartz, and dark biotite or hornblende grains. Commonly found in batholiths and continental shields worldwide.
