Pink Granite

Phaneritic Plutonic Igneous Rock (composed of K-feldspar, Quartz, and Mica)

Hardness: 6-7 Mohs; Color: Pinkish-orange to flesh-red due to Orthoclase feldspar; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarse-grained); Cleavage: Perfect in two directions for the feldspar components.

Physical properties

Hardness: 6-7 Mohs; Color: Pinkish-orange to flesh-red due to Orthoclase feldspar; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarse-grained); Cleavage: Perfect in two directions for the feldspar components.

Formation & geological history

Formed through the slow cooling of silica-rich magma deep underground (plutonic). Typically dates from the Precambrian to Cenozoic eras, appearing in continental crustal environments.

Uses & applications

Extensively used in construction for countertops, monuments, floor tiles, and as crushed stone for road aggregate. Highly valued for its durability and aesthetic appeal.

Geological facts

The pink color specifically indicates a high concentration of potassium feldspar. Famous monuments like the base of the Statue of Liberty and various Egyptian obelisks are crafted from granite.

Field identification & locations

Identify by its interlocking 'salt and pepper' crystalline texture and speckled pink/orange hue. Found globally in batholiths and mountain ranges like the Rockies or Appalachians. Collectors should look for large crystal sizes.
