Physical properties

Formation & geological history
Formed from the slow crystalline cooling of magma beneath the Earth's surface. High potassium-feldspar content gives it the pink hue. This specimen appears water-worn or tumbled, likely from a fluvial or glacial environment.
Uses & applications
Commonly used in construction, countertops, monuments, and as decorative gravel. Polished specimens are used as collectables or 'worry stones'.
Geological facts
The pink color comes specifically from Orthoclase Feldspar. Granite is one of the oldest rocks on Earth, often dating back billions of years, and makes up a significant portion of the continental crust.
Field identification & locations
Identify by its 'salt and pepper' or multicomponent mineral texture and high hardness. Found in continental mountain ranges and regions with glacial deposits.
