Physical properties

Hardness: 6-7 Mohs; Color: Pink, salmon, or reddish-orange due to potassium feldspar; Luster: Dull to vitreous; Crystal structure: Phaneritic (medium-grained crystals visible to the naked eye); Specific gravity: 2.63 - 2.75

Formation & geological history

Formed from the slow crystallization of magma below Earth's surface. High silica content. Can date back hundreds of millions to billions of years, often found in continental crustal shields.

Uses & applications

Widely used in construction, countertops, monuments, and as a decorative landscaping stone. Tumbled pieces like this are common in beginner rock collections.

Geological facts

The pink color comes specifically from Orthoclase Feldspar. Granite is one of the hardest and most durable common stones, which is why it's the primary choice for kitchen surfaces and public monuments.

Field identification & locations

Identify in the field by its 'salt and pepper' or speckled look with distinct pink crystals mixed with translucent quartz and dark biotite or hornblende. Commonly found in mountain ranges and glacial deposits.
