Granite

Coarse-grained, mottled pink, white, and dark minerals with a vitreous-to-dull luster. Quartz hardness is 7 Mohs; feldspars are about 6, and the rock has no consistent cleavage.

An intrusive igneous rock formed as silica-rich magma cooled slowly underground, allowing visible crystals to grow. Granite bodies formed across many geological ages.

Used in building stone, countertops, monuments, paving, and decorative landscaping; small specimens are commonly collected.

Pink areas are likely potassium feldspar, pale areas quartz or plagioclase, and dark flecks commonly biotite or amphibole.

The visible interlocking crystals and speckled appearance are typical of granite; it is common in continental crust and exposed in mountain ranges worldwide. The photo suggests granite, though the small, blurry specimen limits certainty.
