Physical properties
Hardness of 6 on the Mohs scale, predominantly pink, white, gray, or speckled colors, vitreous to dull luster, phaneritic (coarse-grained) crystal structure, poor cleavage, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow crystallization of magma deep beneath the Earth's surface over millions of years, commonly found in continental crust.
Uses & applications
Widely used in construction, monuments, countertops, paving stones, and architectural facing.
Geological facts
Granite is the most common plutonic rock on Earth and forms the core of many major mountain ranges.
Field identification & locations
Easily identified by its distinct interlocking grains of quartz, feldspar, and mica. Found globally in shield areas and mountainous regions. Common field find for rockhounds.
