Weathered granite fragment

Coarse-grained, pale pink-gray rock with visible quartz and feldspar plus dark mica; vitreous to earthy luster, uneven fracture, hardness about 6–7 Mohs, and typical specific gravity 2.6–2.7.

An intrusive igneous rock formed by slow cooling of silica-rich magma deep in the crust, commonly during Precambrian to Phanerozoic mountain-building events; the fragment appears naturally weathered or broken.

Used extensively as dimension stone, building cladding, countertops, monuments, paving, and aggregate; this small fragment has negligible commercial value unless from a documented locality.

Granite’s interlocking crystals make it durable and resistant to abrasion, though feldspar can weather to clay and produce the rough surface visible here.

Common worldwide, especially in continental shields and batholiths. Identify it by its speckled quartz-feldspar-mica texture, lack of layering, and inability to scratch with a steel knife; estimated value: $1–$10 as an ordinary specimen, potentially $10–$30 if locality-documented.
