Physical properties
Hardness: 6-7 (Mohs); Color: Pink, orange-red, with gray and black grains; Luster: Dull to vitreous; Crystal Structure: Phaneritic (visible coarse grains); Cleavage: Perfect in feldspar grains; Specific Gravity: 2.63-2.75
Formation & geological history
Formed by the slow cooling of silica-rich magma deep underground (plutonic). This specimen appears water-worn, likely from a river or glacial deposit. Granites can range from billions to millions of years old.
Uses & applications
Commonly used as decorative gravel, dimension stone for countertops and monuments, and in heavy construction due to its durability.
Geological facts
The pink color is caused by an abundance of potassium feldspar (orthoclase). Granite is the most common rock found in the Earth's continental crust.
Field identification & locations
Identify by its speckled appearance of interlocking crystals. Look for the distinct salmon-pink color combined with glassy quartz and dark flecks of mica or hornblende. Commonly found in mountainous regions or glacial till.
